Gardens in the Mountains – Wasatch Mountains
Botanical travels, Mountains, Plant portraits, Wildflowers of North AmericaWhen hiking on the nearby trails doesn’t suffice anymore, we usually set out toward a mountain area to immerse in the richness of alpine landscapes. Two years ago at the end of July, we travelled to Snowbird, situated in the heart of scenic Wasatch Mountains, Utah. Although better known as a ski resort, during the summer, Snowbird offers an easy and comfortable access to some of the floristic gems of the Utah Rockies.
Snowbird in the Wasatch Mts.
Wasatch Mountains stretch for nearly 200 miles from the Wellsville Mountains on the north, to the Mount Nebo on the south. Elevations range between 4,200 and 11,957 feet (at Mount Timpanogos). Along with jewel-like lakes there are pockets of lush green mountain meadows and areas of alpine tundra. Climate and microclimate differences produce a broad seasonal flowering spread. The basic rock types are made up principally of limestone and dolomite rocks. Soils of widely varying chemical composition are found throughout the area, thus providing a suitable environment for plants that require either acid soil or lime. These diverse habitat conditions make Wasatch Mountains a hotspot for plant endemism. One place where you can spend the whole day, just basking in the sun and admiring wildflowers is the Albion Basin. It is located at the top of glacially carved Little Cottonwood Canyon, above the ski resorts of Alta and Snowbird at over 9,500 feet. During the summer months of July-August there is a spectacular wildflower display in the high-elevation meadows with natural gardens of paintbrush, columbine, lupine, Jacob’s ladder, penstemons, and many more. This is where the Wasatch Wildflower Festival is held every year.
A very interesting plant that I saw for the first time was Pedicularis groenlandica – Elephant’s head (Orobanchaceae), which grows along streams and boggy mountain meadows, forming sometimes large colonies. It has fern-like leaves, mostly basal and dark green stems of about 1 foot high with flowers that look exactly like little magenta-pink elephant heads. Plants blooming for many weeks offer an image that is hard to forget. This beautiful plant is parasitic on the roots of the plants that grow in its vicinity, from which it extracts the nutrients it needs. Because of the parasitic life cycle, it would be probably very difficult to cultivate.
Another first was Aquilegia coerulea – Colorado Blue columbine. It is a columbine with very long spurs and large flowers that can vary in colour from light blue to white (4 varieties in Flora of North America). Usually it grows close to wet stream areas in part-shade, but also can be found on rocky outcrops in full sun. The population we found had almost entirely white flowers. Taking the trail to Cecret Lake and then towards Germania Pass you’ll find a fabulous rocky area hosting Penstemon humilis – Low penstemon (Plantaginaceae). It grows in many-stemmed clumps 4 to 12 ft. tall. The flowers are about 1.5 inches long, colored in every shade of blue from lavender to light sky blue and even magenta. Considering that there are more than 60 species of Penstemon in Utah, I have to mention at least a local endemism, the Wasatch Penstemon – Penstemon cyananthus, which is common in the area, growing on dry, gravelly hillsides. Each plant produces several 2 to 3 ft. tall stems of magnificent blue flowers. You can definitely get your fix if you have agentian blue craving! We even found two very localized forms with white and pink flowers. Another day, on a hike to the Flagstaff Peak, we lost the trail that starts from the Alta Lodge, but were rewarded to find at the top of the ridge clumps of Clematis columbiana var. tenuiloba – Rock Clematis (Ranunculaceae). This is a rhizomatous clematis with aerial stems that are not viny, usually up to 10 cm tall and tufted. Leaves are typically 3-lobed and the flowers are deep pink to violet. It grows on cliffs and rocky summits, usually in open sites. It is a prized rock garden clematis, hard to find to buy, so this year I’m trying my own seeds (hope they’ll come true!).
Lady’s slippers – What’s your size?
Orchids of Bruce Peninsula, Plant portraits, Wildflowers of North AmericaOrchids of Bruce Peninsula II
I was saying earlier that one could spot quite a few Cypripedium spp.- Lady’s slippers, at Singing Sands National Park in Bruce Peninsula. Tread lightly on the trails, watch carefully and maybe you’ll even meet the lady’s slippers fairy from the image below.
Cypripedium reginae – Showy lady’s slipper; it is usually found in fens and swamps and it’s easy to recognize after the bright pink slipper with a round opening. The pink blushing of the pouch can vary greatly in the populations, from deep pink to even, in rare cases, ‘albino’ individuals. As a complement to the flowers are the beautifully ribbed, wide leaves.
Cypripedium arietinum – Ram’s head. Easily recognisable after the unusual shape of the slipper (lip), which also has reddish reticulations. It is flowering a bit earlier than C. reginae and parviflorum, so a visit in late May is advisable.
Cypripedium parviflorum – Yellow lady’s slipper; it is an extremely variable species in regards to flower size and colours. Currently there are 3 varieties recognized in Flora of North America: var. pubescens, var. parviflorum and var. makasin. Personally, I can say that plants growing on drier sites have the slipper usually yellow and larger than those growing in wet habitats (most likely with reddish slipper).
I would strongly advise everyone with the desire and intention of growing orchids in their garden to try to see them first in their native habitat. High prices, of any orchids, are rightly justified by the difficulty to propagate them (mainly in vitro) and the length of time necessary to obtain a flowering size plant (5-7 years). There are many hybrids in cultivation today, which besides interesting flower colours, are said to be more adaptable and faster growing in garden conditions.
A yummy treat – Polygala paucifolia
Plant portraits, Propagation, Wildflowers of North AmericaOne of my goals is to concentrate on the propagation of a few N. American native plants that would be as prized in our garden as any Chinese or S. American novelties. The hype of using native plants in our gardens and landscapes it always cut short by their difficulty to propagate (and by the lack of available seeds collections, of course). Whatever doesn’t fit into the profile of mass-production has been abandoned or perhaps not even tried in cultivation.
Besides serving an ornamental function, expanding into cultivation a few of the hard to find and/or propagate N. American species, would serve also a conservation purpose by maintaining and enriching the genetic material/ biodiversity through sexual propagation.Conservation through cultivation, (aka propagation) has already proved its importance in a few unfortunate cases of species extinct in the wild but saved, at least temporarily, in gardens sanctuaries.
“No, no! The adventures first, explanations take such a dreadful time!” – Lewis Carroll: Alice’s Adventures in Wonderland
OK. Last year we were able to finally collect a few seeds of Polygala paucifolia –Gaywings or Fringed polygala This is a low growing plant found in dry to moist woods, in part shade. It flowers in May-June and the pink-purple flowers are quite unusual – they have 3 short and 2 long wing-like sepals and 3 joined petals with a frilly crest at the tip. Fruit is a capsule. The seeds present an appendage – elaiosome, which is associated with ant dispersal – now you see where I’m going? A bit too late and the seeds are gone. The appendage contains lipids, proteins and starch, which serve as a reward for the ants. They drag the seeds to their nests to feed their youngs on elaiosomes and thus provide the service of dispersal. I bet they are very yummy!
The germination ecology for species from Polygalaceae has not been investigated in detail. I found a study claiming that for P. paucifolia, 4 months of dry storage results in an increase in germination. Other Polygala species are known to require pre-treatments for germination. Anyway, I don’t have that many seeds, so for this year I’ll try two variants: dry storage and moist-cold stratification until sowing in the spring.
We shall see…the seed adventure continues!
Note: Many spring flowers from the temperate climate rely on ants to disperse their seed (myrmecochory – I wouldn’t try pronouncing this); from the very well known: Trillium, Hepatica, Corydalis, Dicentra…
Bristly Sarsaparilla
Plant portraits, Propagation, Wildflowers of North AmericaWhile gazing to the rocky shores of the Georgian Bay in Killarney, one plant kept drawing my attention (and camera) – the bristly sarsaparilla: Aralia hispida. Growing in any small crack of the big granite boulders, with shiny leaves and blackish fruits proudly swinging in the wind, it made me think, again, how many wonderful, garden-worthy, but underutilized native plants are around.
Drought resistant, growing in full sun in rocky, poor substrates, this Aralia could be a prized plant for any garden. The leaves are twice pinnately-divided, and the stem base is covered by bristly hairs and becomes woody persisting through the winter. White-cream flowers appear in June-July in round umbels on stalks that diverge at the end of the stems; they are followed by purplish black fruits resembling a bit the elder fruits (hence the other popular name: dwarf elder). The inflorescences stalks become red, making a nice contrast with the black fruits towards the fall. But enough talk, the pictures are always more convincing…
Not to be confounded with Sarsaparilla – the common name used for various species of Smilax (greenbriers), more particularly for Smilax regelii.
One picture per blossom: A Peony Album
Gardens, Plant portraits“One poem/ per blossom is not enough/ for a peony.” – Ryumin
And if I may add, one picture per blossom would not be enough for a peony either. I realized this at New York Botanical Garden when the herbaceous Paeonia (P. lactiflora) collection was in full bloom. There are plenty of books and websites devoted to peonies. What I find fascinating is how this flower has become so revered in the eastern countries, to the point that peony-viewing was a festive occasion in the Japanese gardens, for example. It was associated with good-luck, prosperity; it was a status and a symbol of good fortune. Peony images can be found in the artwork of many Asian artists, in paintings, tapestry, porcelain and literature. For the peoples from other cultures, the peony may be just a pretty flower, but even so we can all agree that true beauty doesn’t need description. That’s why I put together this album: one picture and one poem per blossom; they are not enough….
Campanula alpina and calcifuge friends
Alpine plants, Botanical travels, Mountains, Plant portraitsPart III of Bucegi Mountains
And after a while, following the trail and botanizing and/or admiring the scenery you’ll make it to the Omu Peak and Omu Chalet. It is time to have a snack, and finding a place to sit down (outside) is easily done. Careful though – because you’ll be surrounded by Campanula alpina, Primula minima, and clumps of Gentina frigida with the occasional Soldanella pusilla among them!
Omu hut
Campanula alpina (subsp. alpina, to be more precise) is a very small Campanula but with big flowers, which looks as if emerging straight from the ground. It forms 5-10 cm tall flowering stems with lots of hanging bells in various shades of blue, and we also found a white one. Some say it is not strictly calcifuge, but given its choice of plant-buddies, probably a lime free substrate would be best for its cultivation. Luckily we found a few capsules to share, and it would be good to see at least a few of us successfully growing it in our rock gardens. I have never seen it offered, but this Campanula deserves a ‘five-star’ rank among the other rock garden bellflowers!
There were just a few small clumps of Gentiana frigida, growing only up to 10 cm, with the flowers held in erect, terminal clusters. Apparently, the colour can vary from white to lemon yellow, with blue stripes and spots. Flowering so late in the season, it makes me wonder if ever gets to produce mature seeds as it is not unusual to have snow there in September. It is probably the lack of available seeds that makes it very scarce in cultivation. Primula minima is indeed a minimalist Primula, so little yet forming such large mats that in some areas one has no choice but to step on it. The flowers, which are quite big, were gone and the capsules were just about to mature. Apparently it can be grown from seeds and does well in a gritty, acid, humus-rich mixture, but the big problem in cultivation is managing to have it flower properly. Soldanella pusilla is the only calcifuge from the Snowbells group and has pink to violet flowers. As I don’t have many pictures, I’ll just move forward to another Carpathian endemic: Rhododendron kotschyi. This is a low spreading rhododendron that grows up to 20-30 cm, usually in groups that can occasionally cover large areas. It is an unforgettable sight when in flower, with large, pink, fragrant flowers in late May- June! We were happy enough to see it again, even if just for the glossy foliage.
Blossoms of snow
Alpine plants, Botanical travels, Mountains, Plant portraitsPart V of Bucegi Mountains
Although not considered an emblem flower of the Carpathian Mts., Leontopodium alpinum – the Alps Edelweiss is much sought after. Whenever we had friends coming with us, they always wanted to see it growing on the mountain. It is not common everywhere, but we found it one day while hiking on Valea Cerbului towards a favourite place of ours, which can be reached by diverting from the marked trail leading to the plateau. The popular German name: edelweiss comes from ‘edel’-noble and ‘weiss’- white, while the scientific one: Leontopodium means ‘lion’s paw’. In Romanian the common name is: Queen’s flower and like in many other countries it is a protected species. Shortly lived in cultivation but it can be grown form seed.
On the rich subalpine meadows at the bottom of the cliffs, more snow blossoms showed up – of our favourite Dianthus: Dianthus petraeus (subsp. petraeus), with fringed, white, fragrant flowers. Usually growing in crevices of big boulders or on the mountain slopes, it was unfortunately just at the end of flowering but the perfume from a few late flowers was a more than enough remainder. Then we found the endemic Dianthus tenuifolius, flowering abundantly in the sub-alpine meadow and also with some seeds as well; bright, pink flowers on 15-20 cm tall branched stems. And just when you think it cannot get any better, clumps of deep blue flowers of a rare endemic gentian started to appear: Gentiana phlogifolia (syn. G. cruciata subsp. phlogifolia). Flowering from July to September, it grows up to 20 cm but with somewhat trailing stems under the weight of the flowers.
Going down on the memory lane by looking at the pictures, and also leafing through Flora of Romania, I realized that the very nice Centaurea pinnatifida, that we’ve seen growing in the same place, is also endemic! Wishing that they will all bloom and grow forever on that magic mountain!
And down we go…Aquilegia nigricans
Alpine plants, Botanical travels, Mountains, Plant portraitsPart IV of Bucegi Mountains
Before leaving the Bucegi Plateau, one more look at the grassland plant communities in the alpine areas revels associations of Carex, Luzula, Festuca, Sesleria, Agrostis, Nardus,and Poa species – lots of them! In the summer time you’ll also find Campanula serrata another Carpathian endemic, flowering in these alpine and sub-alpine meadows, with typical blue flowers in paniculate inflorescences. Usually when beginning to descend, a cool breeze of nostalgia will come swiping over you. It is time to say goodbye and who knows when you’ll be back – but luckily many other plant species will sweeten the hike down for you. One option to descend from the Bucegi Plateau is to hike down on Jepilor Valley. It is quite steep at times but there is so much to see along the way!
You’ll most surely see the fluffy fruit heads of the alpine pasque flower – Pulsatilla alba (syn. Pulsatilla alpina subsp. alpicola), which forms clumps of finely divided leaves and has large, white flowers, hence the name alba. There is little chance to see it in flower, because conditions are too dangerous in this area in the springtime, but the fluffy fruit heads are enjoyable enough. Loiseleuria procumbens – creeping azalea, was nearby too, so we should assume that this Pulsatilla prefers a lime-free substrate. Not very abundant in the area, scarce would be better said, is Aquilegia nigricans. In late July-August it is past its flowering time, however at high elevations one may get lucky and enjoy one last flower – deep blue, that some describe almost as black, perhaps taking into consideration its name (‘nigricans’). Like with many species growing in somewhat unusual or not too easily accessible places, some descriptions on various websites are imaginary or applied based on the copy & paste function and should be careful considered.
The descending trail follows for a while high rocky walls, adorned with various species, among which a nowadays common garden campanula: Campanula carpatica. Long taken into cultivation, it still has a particular charm when seen growing in its native ‘land’ – rocks that is. Another member of Fam. Campanulaceae, but not as widely cultivated is Phyteuma orbiculare. Does not look like bellflowers, but it is a very interesting genus with quite a few species good to grow in the rock garden. And one more species usually seen in flower from July to September is Aconithum anthora, a yellow monkshood found cultivated sometimes. The really large, showy yellow flowers are easily seen from far away – Don’t forget that it belongs to the Wolfsbane family though! A few more species are presented in the gallery (hard to abstain :) – I am sure Carlina acaulis would raise a few eyebrows. It’s easy to recognize the most beautiful of the thistles, called alpine or stemless thistle. It forms large rosettes with spiny leaves, usually basking in the sun and the equally large flowerhead with silvery-white ray florets is very handsome and attracts pollinators. Its roots were employed in herbal medicine as a diuretic and cold remedy.
Still botanizing in the Bucegi Plateau
Alpine plants, Botanical travels, Mountains, Plant portraitsGeum reptans is an alpine gem of which I was able to collect a few seeds. Growing in crevices and spreading in mats over boulders, it was already past flowering during late July, and its ornamental fluffy seed heads were getting pink. Although also admired for its yellow flowers, I find the pinnate, fernlike foliage very beautiful in itself. Called ‘the best of its race of mountain avens’ by Jim Jermyn, it is most definitely calcifuge requiring a perfectly drained mixture and full sun exposure – perfect for a scree garden.
Near the Geum reptans, small tufts of Armeria alpina stood out on top of the rocks, and then, fiercely competing with them for our attention, Dianthus glacialis, with its brilliant pink flowers, was making it very hard to concentrate on taking pictures! Dianthus glacialis in flower is a must see, at least once in a lifetime. Small green cushions covered in almost stemless pink flowers, defy description. There are two subspecies, glacialis and gelidus, the later being a Romanian endemic. The differences between them are quite minute; without going into details, subsp. gelidus has bigger flowers with a more intense pink colour, and it seems that the clumps we found belonged to this subspecies. To change the colour spectrum, clumps of two wonderful Asteraceae with white flowers: Achillea schuri and Anthemis carpatica were sprinkled on the rocky slopes, blooming profusely. Anthemis carpatica is already taken into cultivation and apparently adapts well to full sun and calcareous substrates, while Achillea schuri, endemic to Romania, has still to make its way into the gardening world.
Whenever the trail goes close to stone walls and outcrops, the delightful Campanula cochlearifolia greets you from above with its thimble-like delicate, blue flowers. It is not a pretentious plant to cultivate either, and can even overcome its boundaries if not restricted between some rocks. Among the species with violet or mauve flowers I have to mention Calamintha alpina subsp. baumgarteni (syn. Acinos alpinus subsp. alpinus). Considered a chamaephyte, it has a woody stem with small leaves and mauve flowers typical of the Lamiaceae family. On the other hand, the genus Oxytropis is not a stranger to rock gardeners, and Oxytropis halleri is a wonderful example with its violet flowers and dense pinnate foliage. And of course, it cannot be a mountain ‘story’ without a Saxifrage. Quite a few species are abounding in the Bucegi. Saxifraga paniculata seemed very happy in the Plateau, flowering in big colonies at margins of the path, as well as Saxifraga moschata, which has small rosettes, with finely divided leaves and yellow, fragrant flowers.
And to be continued…
Climbing Monks…hoods
Gardens, Plant portraitsYet another subject that I don’t have enough time to dedicate – the climbing Aconitum species. While the old fashioned monkshoods have been in the gardens and are well known for a long time (yes, despite the fact that they are highly poisonous), the climbing ones are still to raise a few eyebrows. Most of them, like A. hemsleyanum, A. volubile, and A. uncinatum with the usual blue flowers are a bit more common than this one that makes me start the conversation: Aconitum alboviolaceum – from China, Korea, Far East Russia, where it grows in “forest, scrub in valleys, mountains; 300-1400 m” (Flora of China vol.6). Two varieties are recognized: var. alboviolaceum: with twining stems – 100-250 cm and var. erectum – stems up to 30 cm tall.
Aconitum alboviolaceum var. alboviolaceum
Raised from seed and in its third year now, it twined very gracefully around a snake bark maple in the Display Garden at Lost Horizons, without becoming too cumbersome. In a perfect match with the snake bark, rows of monks with pink&white hoods are now, slowly climbing up….
Alpine Golden Nuggets from Wrightman Alpines
Gardens, Plant portraitsThe Plant Gold Rush continues with the most precious of finds: the alpine golden nuggets. We found them at Wrightman Alpines during their open house last Sunday. It had been a while since I was lucky to admire their Saxifrages in flower, so we made another trip that turned out into a photography extravaganza. Many ‘golden nuggets’ were either in flower or at their best foliage; we took advantage of our most kind hosts, Irene and Harvey Wrightman, and poked around every corner of their wonderful rockery garden and nursery. Even for a plant connoisseur the richness of plant species they have can be a bit overwhelming to digest, so I’ll take it slow and there’ll be more to come…
Paeonia suffruticosa ssp. rockii
At this time of the year, after admiring the most impressive clumps of Paeonia suffruticosa spp. rockii, the best would be to explore the rock gardens around the house before heading into the hoop houses (although being very detailed people we did the other way around).
Enjoy a few images from Wrightman Alpines Nursery rock gardens

Of course, we came home very grateful and with a few gifted golden nuggets; to show off just one of them:
Scutellaria orientalis ssp. pinnatifida – a very floriferous and bright Scutellaria (from Turkey at 2500 m)
The wonderful day spent among the plethora of alpine species (native and non-natives) brought to my mind a few places we traveled to and I wrote about – see the Botanical Trailblazers page. Gold mines full of ‘golden nuggets’ await to be discovered almost everywhere – start exploring!
And then there were the Saxifrages…
Gardens, Plant portraits, PropagationThe Latin word saxifraga means literally “stone-breaker”, from Latin saxum (“rock” or “stone”) + frangere (“to break”). Pliny the Elder thought the plant was named like this because at the time it was given to dissolve gallstones (another example of the Doctrine of Signatures). Even so, Saxifraga is a very good name for a plant growing in rock crevices.
Saxifraga ‘Redpoll’
Some of my regular readers might have noticed my penchant for mountains, and of course, everything that grows on them. The seed collections from the Carpathian Mts. we did last summer, my limited garden space (at some point there is no other way to expand but UP), and the fact that every year I plan to do it and it never happens, all combined together and I finally made it to the only nursery specialized in alpine plants from Ontario: Wrightman Alpines .
Alpine house with Saxifraga and many other species
It is a small size operation (mail-order) but growing a vast array of alpine plants from all over the world. On their website, besides perusing the catalogue, with some species in very short supply, you can watch a few interesting videos about building clay crevice gardens, planting tufa and much more. Alas, this cold month of March made it that many species were behind their usual growth, but to put things into balance, the Saxifrages were in flower. Skilfully grown in small tufa pieces by Harvey Wrightman, they were looking like miniatural rock gardens in themselves.
Saxifraga ‘Athena’
Saxifraga cochlearis ‘Minor’
Saxifraga oppositifolia ‘Florissa’
The genus Saxifraga is quite large, comprising a wide range of mostly perennial plants, many of which are alpines. According to the Saxifraga Society there are some 480 known species and countless garden hybrids. The sections that are of garden interest are: the ‘mossies’ (section Saxifraga), the ‘silvers (section Ligulatae) and the Kabschia and Engleria subsections (of section Porphyrion).
Saxifraga ‘Allendale Charm’
Saxifraga oppositifolia ‘Theodor’
Saxifraga ‘Premsyl Orac’
Now, if I made you think I know what I’m talking about, you are wrong (in this case). When I’ll be done with the many other genera I’m working on, I’ll get to the Saxifraga too, but that might be a long time from now. Unless you really need a botanical challenge in your life, I suggest that you do like me: try to have fun growing a few of them in your rock garden.

For the connoisseurs, I cannot end without showing a real alpine gem: Dionysia tapetoides – a cliff-dweller, native from Afghanistan, hard to grow and equally hard to find.

Sunday Phlog: Never enough Gentians
Gardens, Plant portraitsFlowering faithfully from spring through summer and late fall, the Gentians are my most beloved flowers. Although I am usually associating them with a mountainous environment, there are plenty of species/varieties growing happily in ordinary garden conditions. This gallery contains Gentiana species and varieties from our travels and from Lost Horizons Nursery (where a few are available to purchase) and it will be updated gradually.
And if you are crazy like me about Gentianaceae please visit The Gentian Research Network.
Sunday Phlog: More cinnamon, please?
Gardens, Plant portraitsYeah, I have to show off more of the Roscoea ‘Cinnamon Stick’, it’s tooooo beautiful…
Roscoea purpurea ‘Cinnamon Stick’
The first species to flower is also one of the most cultivated – Roscoea cautleoides. Typically it has pale yellow flowers, but there are also forms with pink flowers.
Roscoea cautleoides
Roscoea cautleoides ‘Jeffrey Thomas’ – flowers with an enlarged labellum, primrose yellow and the hood with a deeper yellow
Roscoea auriculata – native of Nepal, Sikkim and Xizang, has large flowers usually deep violet or purple and consistently auriculate (eared) leaves on the pseudostem. It is sometimes confused with R. purpurea, however it flowers earlier and it has white staminodes and a strongly downward-facing labellum.

Grown from a batch of seedlings supposedly of R. cautleoides, it was a very pleasant surprise for us to discover that we have a new species in cultivation: Roscoea scillifolia f. atropurpurea. This one seems to be rare not only in cultivation but in the wild too, so it is fair to say that we just got lucky!

A Yellow Giant: Gentiana lutea
Gardens, Medicinal plants, Plant portraitsSome of you may be surprised to find out that the following image belongs to a gentian, but it’s true. This is Gentiana lutea (Yellow gentian, Bitter Root), native to the mountainous regions of central and southern Europe (Carpathians, Alps, Pyrenees…), where usually grows in alpine and sub-alpine meadows on calcareous soils. It is a tall perennial, reaching 1-2 m, with large leaves arranged in a basal rosette until flowering. The yellow flowers are atypical for a gentian, with corolla deeply divided in 5-7 narrow petals, and disposed in terminal and axillary clusters.
Gentiana lutea flowers
Gentiana lutea has been used for centuries as a medicinal plant, and to flavour alcoholic drinks commonly known as bitters, which are very common and widely used in Germany, France, Switzerland and Italy. For this purpose, the roots and rhizomes are collected in late fall and dried, practice that has lead to over-collecting and brought the species to endangered lists in many countries. The principal medicinal use of the yellow gentian is for digestive disorders due to its bitter compounds, among which the gentiopicrin, is one of the most bitter natural compounds known.
Apart for its medicinal virtues, it is an impressive perennial, a focal point for a sunny perennial garden. It is a rare find, so hurry up and spread the word! Flowers in June-July or in July-August at high elevations. Needless to say that it is very hardy. Propagation has to be done by seed.
Gentiana lutea in the Display Garden at Lost Horizons
Of botanical interest: Despite its atypical flowers Gentiana lutea it is the type species of the genus Gentiana! [The generic type is a representative species that is selected when a genus is described].
I’ll have more on Gentiana lutea, as the few seeds I collected from the Carpathians Mts. will germinate (fingers crossed) and also I hope I’ll manage to collect more seeds in the future.
Meanwhile, you can see the yellow giant in flower by visiting the Lost Horizons Display Garden in July (and sometimes a few plants are available for sale).
Who’s afraid of the Arisaemas?
Gardens, Plant portraitsIn the garden world the common ‘everyday’ can vanish somewhere between real and surreal; for sure Arisaemas are to blame for this. Mysterious and animistic creatures, they are permanently watching us, even from the underground. At Lost Horizons Nursery there are quite a few Arisaema species (Cobra lilies or Jack-in-the-pulpits) around; sometimes benevolent and sometimes mischievous you’ll find them everywhere: in small seedling trays to pots, stock beds or in the display gardens.
Arisaema ringens
Arisaema ringens from the galeate section of cobra lilies is worth growing only for the huge, trifoliolate, glossy, and leathery leaves. The thick spathe with green and purple stripes resembles a cobra head rising up from the shade, ready to attack garden intruders. The spathe-limb is described botanically as galeate (galea – means helmet), and can be green or purple with white stripes and revolute green or purple margins. The spadix is either male or female. Origin: Japan, S. Korea, Taiwan, and E China. The only regret that someone can have about A. ringens is that it rarely produces seeds. Maybe the right pollinators are not around, and we also need to have the two partners together in order to have babies, aka. seeds (at least in most cases).

Another species with galeate spathe-limb (helmet-like) is A. franchetianum. It has 1 or 2 trifoliolate leaves with bluish green, ovate leaflets and the inflorescence appears below the leaf, like in A. ringens. Arisaema franchetianum ‘Hugo’ has the spathe-limb deep purple with white stripes and its tip is ending in a 20 cm long tail-like apex. The spadix is either male or female, exceptionally bisexual – but let’s not get started on the Arisaemas gender variability now…

Arisaema franchetianum doesn’t require that much shade like other Arisaemas; in its original habitat is actually growing in “ open sunny sites among boulders and scrubs, along roadsides” (SW China, NE India, and N Myanmar). Here you have it, one Arisaema that doesn’t have to be in the woodland garden!

Do not be afraid of the Arisaemas, take my example – Good and not so good things happening around the garden?
Blame them all on the Arisaemas!
