I’ve started to put together a list with species easy to grow from seeds as a way to provide info and encouragement to those who are at the beginning of their seeds adventures. The list will see additions as we go.

Let’s begin with Edraianthus graminifolius; yeah, I am not starting with A, just because I don’t feel like it :)

Edraianthus graminifolius – grassy bells belongs to the Campanula family and like its name suggests, has linear, grassy-looking leaves and large,

Edraianthus graminifolius

blue flowers, in terminal clusters in May-June. The foliage remains tight and low at about 15 cm but the flowering stems are spreading/trailing so it needs its space ;)
An absolutely delightful and easy going plant, as long as grown in full sun/well drained locations. You don’t really need a rock garden for it; just keep in mind its growth habit and place it in a suitable spot.

Growing for the first time from seeds, or just want something fast and easy? Try something from the list below. ‘Easy to grow from seeds’ means:
– easy to germinate & in large percentage
– seedlings that aren’t fussy to grow
– also, easy going plants in the garden, as long as provided with the required conditions.

I will avoid the so called two-stage germinators (although all you have to do is wait) or others that I never germinate/grow myself, species with naturally low germination rates, cases where the seedlings need special care or the ones I’m not quite sure about.

Honestly, I had no intention to write another post so soon, but plants need to be shown at their best moments. And, Amsonia hubrichtii, the Arkansas bluestar is absolutely radiant right now.

Amsonia hubrichtii in late fall

Depending how much sun receives it may also take a russet hue (notice the capsules).

I won’t wonder again about why is not cultivated more; the images speak for themselves. It is a foliage plant by definition, the thread- like leaves will combine beautifully with almost anything else; those who want more flowery display should plant other perennials close to it and let them complement/weave through the delicate foliage.

The flowers are pale blue, not very noticeable but a nice addition.

With Delphinium likiangense; probably larkspurs (Consolida regalis) would make for a nice combination as well.

Without thinking much, one year I planted Dahlia coccinea behind it; now it has become the rule.

The seeds are quite particular, like of other Amsonias (Fam. Apocynaceae); the fruits (capsules) can be spotted in one image above.

Amsonia hubrichtii seeds

PS. It is a bit late to emerge in the spring; planting a bunch of small spring bulbs & daffodils close to the clump will do the trick ;)

 

Another belated Friday’s seeds would have been unacceptable, so a plant portrait instead (seeds included ;) about the cranberry – Vaccinium macrocarpon, American cranberry.

The Cranberry is a North American symbol. Recently I’ve seen it growing in the wild and asked myself how many people actually know how the plant looks like?

Vaccinium macrocarpon fruit

It is very surprising to see that the large fruits are formed on a small trailing vine, which has thin, graceful branches. Is this indeed The cranberry?

Vaccinium macrocarpon

Yes, it is; after all ‘macrocarpon’ means ‘large fruit’.
Another species, Vaccinium oxycoccos, the small cranberry, is very similar and distinguishable by its pointed leaves (and few other details). The cranberries are specific wetlands species: they grow on swamps, fens, and occasionally on glacial deposits in kettle holes on shorelines (like shown in the picture). Usually will form mats on Sphagnum moss; leaves are shiny green/glaucous beneath and turn bright red in the fall.

The American cranberry can be found from Manitoba to Newfoundland, and south into the mid-western and eastern U.S. Probably in some areas fruits are still collected in the wild but most came from commercial operations. It was one of the first medicinal plant crop to be grown commercially in the U.S.; maybe in Canada as well.

Traditionally, Native people have gathered and consumed the fresh fruits for their vitamin C content and also used them dried and mixed with fat/dried meat and fish.
To note only few of the modern utilizations: they are used mainly for juice and pie making, jams, dried fruits, and for naturopathic preparations (bladder and kidney infections).

Have a bog/wet, acidic area in the garden? – do not hesitate to grow this lovely North American shrub!

 

In this part of the world, the heat & humidity combined together can be quite unbearable. Today, we reached around 38C, with the humidex!
Even the little Roscoea tibetica f. atropurpurea couldn’t take it anymore and the first capsule bursted out in desperation. Two more to follow…

Roscoea tibetica f. atropurpurea with split capsule

I talked about this Roscoea a few times; a cute little thing and a curiosity. It shows up very late (June), produces only few flowers and it is so small that it needs a special place to be seen. Plus, the capsules split in a most unattractive way. Still, I found it charming :) Don’t you?

Roscoea tibetica f. atropurpurea – measured last year

White on blue is a refreshing combo. Yesterday, amidst the heat wave I took few pictures of Aconitum ‘Ivorine’ just starting flowering.
Pure white, tinged with green flowers on sturdy stems make this Aconitum very appealing.  The bluish background provided by Juniperus ‘Wichita’ is pure serendipity – most of my plants were planted where I could find a proper space in this new garden without much thinking of colour combinations.

Aconitum septentrionale ‘Ivorine’

It doesn’t clump excessively, which is unfortunate; I could use more seeds, so this is the next ‘ivory’ generation! Very easy to germinate if the seeds are sown fresh or kept moist and allowed a warm/cold cycle. The pots can be brought indoors around February to germinate and grown under lights will achieve a better growth by June. I had no more space available this year so they germinated outside somewhere beginning of May.

Aconitum septentrionale ‘Ivorine’ freshly transplanted seedlings

 

 

 

Growing annual plants is very satisfying – they germinate, grow, flower and set seeds in one season; some will also self-seed themselves for the next year; nothing to worry about throughout the winter…I can understand the attraction. But I still like to grow perennials ;))

Sometimes I make exceptions – and Sedum atratum is one notable because I collected the seeds from a place in the Carpathians that is not easy to reach; it reminds me about ‘my mountain’, and belongs to the ‘little plants’ category.

Sedum atratum ssp. atratum in the Carpathian Mts.

Last year some nocturnal animal took a snack from a little clump growing at the edge of the rockery; luckily a few seeds were already into the safety of the tufa rocks and I can continue to enjoy it. Maybe even collect a few seeds later.

Sedum atratum ssp. atratum among Dryas octopetala ‘Tundra Pygmy’

Sedum atratum ssp. atratum is an annual species, with the mention that I’ve seen non-flowering rosettes and most likely also behaves as a biennial; from the mountains of South and Central Europe.
It is great in a rockery or scree area, showing here in there, without bothering other species; small, fleshy stems and leaves, which turn deep red later in the season.
Best to scatter the seeds in the desired place, in late fall or early spring.

 

Most probably the first plant I grew successfully from seeds (that is, which I saw it flowering :) was an Aquilegia. I don’t remember precisely which one and it doesn’t matter; I like them all very much. They are easy to grow, provide a whole array of heights/colours and are good pollinator plants.

Yes, some are short lived, and yes, most will be attacked by leafminer, and of course, they hybridize and not all seedlings come true to the mother plant, but I still like them very much.

Aquilegia flabellata var. pumila has few of the above mentioned flaws: it usually comes true from seeds, and the thick, leathery foliage won’t be affected by the leafminer (or very weak attack); all ‘flabellatas’ could be grown just for their handsome, fan-shaped foliage.

Aquilegia flabellata var.pumila – cute as a ‘button’ ; grown from seeds of course

 

A. flabelata ‘Nana Alba’ will be flowering soon…
Update – and it did, not a ‘nana’ but very beautiful!

 

Myriads of Mitella diphylla flowers are still falling from the sky. I noticed that not too many people are familiar with this dainty North American woodlander; what a pity…

It can be found in deciduous woodlands in part shaded areas, most often at the edges of the forest; easily noticeable despite its small flowers, it will flower somewhere at the beginning of May. A better timetable is to consider that it flowers at the same time with Trillium grandiflorum, Uvularia grandiflora and Coptis trifolia.

Mitella diphylla, Two-leaved bishop’s cap (Fam. Saxifragaceae) – Tall flowering stems carrying small, fringed, snowflakes shaped flowers above a pair of leaves. Fruits are dehiscent capsules with many small, black seeds.

Mitella is not an easy subject to capture on camera

What I like even more about it is that the basal leaves are evergreen; a most useful character in our climate with long flowerless periods. I cannot take a picture in the garden right now, but I have one from the previous garden showing it together with Cyclamen hederifolium and Hepatica in late November.

Mitella diphylla, Cyclamen and Hepatica foliage in November

Propagation: easy from seeds (sown in the fall) and mine has started to flower in the third year. After it gets established it can also be divided (it forms a rather tight clump so there is no worry about potential invasiveness).

Mitella diphylla seeds

The genus name Mitella comes from the Greek ‘mitra’= cap and the common name bishop’s cap or mitrewort refers to the cap-shaped fruit.

Growing from seeds is always full of surprises, especially for first time sowings, like in this case for Iris pumila.

Iris pumila – a dwarf, early spring flowering, bearded Iris with a wild distribution from Central Europe to the Caucasus. The large flowers can be violet, blue, purple, yellow, or in various combinations like it naturally happens in wild populations; it is super hardy and excellent for the rockery, or a sunny border.

For best germination, most sources suggest soaking the seeds and providing about 4 weeks warm and then a longer (few months) cold period. So, my plan was to keep the sowings the furnace room for 3-4 weeks (+/- 23C day/ 17C night) and then place the pots outside under snow for the remaining of the winter. I sowed on Dec. 19th – and a couple of days ago (Jan. 5)…surprise! I found some pots with the first shoots were out. The plan has changed of course, and my light stand will be up very soon :)

Iris pumila – seeds soaked, sown on Dec.19th at warm – first signs of germination Jan. 5th (few even sooner)

The pots contain seeds of differently coloured specimens, although this little Iris can provide even more surprises colour-wise!

I don’t know if the seeds will germinate in the same way after going into a deeper dormancy, but this is still a good time to sow – and few fresh seeds are still available in the shop!

Sooke Coast Trail – part 1

At this time of year we are in need of sunny/flowery images, so I’ll quit the propagation stories for a while (I am sure some readers got heavily bored ;). Chance made it that I got to visit Victoria (situated on the southern part of Vancouver Island) in late May, but never got to sort through the many pictures; few posts will take care of this now ;)

A short note for those who are not familiar with the region: the southern part of Vancouver Island constitutes the northern growing limit for many species, which are common otherwise on the US west coast down to the Californian coastal mountains. Victoria is considered the mildest city in Canada and enjoys a sub-mediterranean climate (yes you hear me well!) with mild winters (snow is a very rare event), rainy springs and falls and dry summers (hardiness considered, zone 7-8).

The first highly recommended hiking destination, in a short driving distance from Victoria, is the Sooke area. There are a few trails available, which can be done partially or entirely. The Coast Trail in East Sooke Regional Park was particularly impressive (follow link to see map and read more).

view-from-sooke-coast-trail-2

View from Sooke Coast Trail

Excellent views are opening all along the trail, which follows the rocky coast, only with a few passages going deep into the forest (usually to go around a pocket beach). In between taking pictures and stopping to admire the wild, rugged landscape, time flies; I would say that at least two days are necessary to get a good grasp of its beauty.  It is very hard to choose only a few pictures to show.

Plants speaking, the first species that makes you go – WoW! Is the Pacific Madrone – Arbutus menziesii. Any time I encounter in the wild a species previously known only from picture, there is a special feeling, same like meeting a person known previously only from correspondence. I couldn’t shake hands with the Arbutus :) but I was happy to brush my hand over the exquisite cinnamon/red, exfoliating bark.

arbutus-menziesii

Arbutus menziesii on Sooke Coast Trail – Pacific Madrone, Arbutus

Pacific Madrone/Arbutus is an evergreen tree with many other qualities, glossy leaves and creamy clusters of flowers (attracting many pollinators) followed by red fruits; all making for a most beautiful tree. And there is more – the trunk and branches are twisting in various ways, to the point that sometimes they will hug and gracefully slide along the rocks’ contour. Its native range extends from:  SW  Vancouver Island to south Baja California. It is found growing in dry open forests, rocky slopes, on coarse or shallow soils.

arbutus-menziesii-1

Arbutus menziesii

Another ‘staple’ species of the region is Sedum spathulifolium – the broadleaf stonecrop. It seems able to grow absolutely everywhere: on moss-layered rocks, decomposed tree trunks, wind blasted rocks in full sun or cascading over shaded boulders. Truly spectacular! Probably half of my pictures contain this Sedum in various plant-associations. I liked it best together with Cladonia or a Cladina sp. (the reindeer moss); the white-silvery, lacy lichen bringing out the beauty of the bluish foliage and the contrasting red stems & yellow flowers.

This post is getting a bit too long so more to follow…

I’ve repotted some fine young Jeffersonia seedlings two weeks ago and now it took me a great pleasure to write this post. Jeffersonia diphylla (Twinleaf) is a wonderful NA species that should be mandatory for all gardens; the pictures show it in its glory at Aspen Grove Gardens.

A delight from early spring (April) to fall, and notice that although a woodland species, it is grown with a fair amount of sun and does very well.

Just like bulbous/tuberous species, the ones that form rhizomes need 2-3+ years to develop their root system before they will start flowering. The faster/better their rhizome grows, the sooner they will flower. Again, it is very easy to underestimate the size of a seedling root system. This is why the repotting is very important and can be done either in the fall or spring. Each period has its pros and cons, but for our climate at least, I incline for the late fall (after they’ve gone dormant).

 I will outline next the whole process from sowing to repotting the seedlings:

  • Sow the seeds as soon as possible after collecting, or keep moist at room temperature; however, keep in mind that this species doesn’t keep too well in moist storage and seeds are available (if) for a short period.
  • Sow as usual or use my ‘space saving method’ – also very practical for someone who doesn’t want to have one pot sitting around by itself. Sow all the seeds in one larger pot and ‘plant’ the pot in the ground (in late fall I added some mulch on top, which I’ll remove in the spring).

Tip: ‘plant’ the pot close to a shrub/tall perennial plant that will shelter and shade the seedlings; also close to the house so you won’t forget about it (the seedlings require extra watering during dry spells). Mine was close/beneath an old Peony, unfortunately I don’t have a picture.

  • Seeds have germinated somewhere in May (about 100% by the look of them). Foliage wise, not much it will happen the whole season, only one shoot with the cotyledon leaves.

  • Use a diluted fertilizer once in a while (only if you remember…), water regularly; nothing else to do till late fall.
  • By late October- early November watch for signs of dormancy.
  • Let the pot dry out a bit.
  • Tip off the whole content and gently separate the seedlings (don’t forget to congratulate yourself, take pictures, eat some chocolate/cake…)

Jeffersonia diphylla: one-year old seedlings ‘extracted’ from the pot

  • Repot in a fresh potting mix (I don’t have any ‘special’ formulas); one or more seedlings/pot. Planting 2-3 seedlings/larger pot will make a ‘clump’ faster.
jeffersonia-diphylla-one-year-seedlings-in-late-fall1

Jeffersonia diphylla seedlings showing an extensive root system after one season of growth and a well formed bud.

  • Water well, and if it’s late November, that’s all they need.
  • Storage: cold frame, or again, ‘plant’ the pot(s) in the ground and throw mulch/few leaves on top.
jeffersonia-diphylla-repotted-one-year-seedlings

Jeffersonia diphylla: repotted seedlings ( I have 2-3/pot)

  • Another good option is to grow them one more year in the same pot; this way the seedlings will be larger in size and easier to handle, especially for those who are not used with transplanting little seedlings.

Special thanks to Robert Pavlis @ Aspen Grove Gardens, for growing this beautiful, ‘photogenic’ species and providing the material for this post, i.e. the Jeffersonia seeds :)

You can apply the same technique for growing its Asian counterpart, Jeffersonia dubia. Next to come – how to easily grow from seeds Aconitum alboviolaceum…stay tuned.

A rainy day, perfect to show my young Chinese Podophyllums: Podophyllum delavayi and P. pleianthum x versipelle. They don’t like the cold very much but surely enjoy the moisture whenever possible.

podophyllum-delavayi

Podophyllum delavayi

The few that I manage to transplant in larger pots in early summer, obviously fared better than the ones left in small ones. This is happening with all rhizomes forming species, which need large pots in order to develop well. Note taken of the ‘thorny’ problem of quantity over quality…

podophyllum-pleianthum-x-versipelle

Podophyllum pleianthum x versipelle

Talking Chinese Podophyllum spp., I have the chance to show a ‘freshly’ taken image with seeds of P. aurantiocaule ssp. aurantiocaule.

podophyllum-aurantiocaule-seeds

Podophyllum aurantiocaule ssp. aurantiocaule seeds

Interesting to see how different the seeds are comparing with others (see in the featured image germinated seeds of P. pleianthum x versipelle). This species belongs to Section Paradysosma and it said that combines the leaf shape of Sect. Dysosma (P. pleianthum, versipelle…) with the floral characters of Sect. Hexandra (P. hexandrum). The seeds are very similar with those of P. hexandrum, that’s for sure.

Looking fw to see the ‘youngsters’ next year!!!

And…I have few seeds to spare for those interested, enter the shop here: Podophyllum aurantiocaule ssp. aurantiocaule

Germination for all: clean the seeds from the fleshy fruits and sow right away (late fall); or place the seeds in cold/moist stratification and sow when they show signs of germination (early spring).

 

Iris dichotoma flowers, the Vesper Iris, formerly Pardanthopsis, open ‘religiously’ in the afternoon around 4 pm. By late evening, they are already withered. Nonetheless they are beautiful and it is exciting to watch. It makes you wonder – why the short period of flowering?

Iris dichotoma2

According with an article from the Journal of Experimental Botany: “flower opening and closure are traits of a reproductive syndrome, as it allows pollen removal/and or pollination”. Although a peculiar species, the vesper iris is not given as an example in the study.

Iris dichotoma – first year flowering from seeds; super easy to grow

Those interested can read about the mechanism of opening and closure, carbohydrate metabolism, hormonal regulation and more here – Flower opening and closure: a review, Wouter G. van Doorn, Uulke van Meeteren.

Note on Vesper
In many Christian denominations, vespers is the name used for the evening prayer service. From Greek ‘hespera’ and Latin ‘vesper’ = evening.

 

Gentiana cachemirica

As it happens, species that flower successively over a long period of time will often have the first seeds ‘ready’ while still in bloom. Last evening, ahead of another front of thundershowers, I had a look around the garden and, you don’t say, I found the first seed capsules of Gentiana cachemirica!

Not often cultivated and often misnamed in the trade, this is an alpine gentian endemic from Pakistan and Kashmir (hence the proclaimed common name of Kashmir gentian).  Let’s see it again:

Gentiana cachemirica - flower open

Gentiana cachemirica

It flowers in late summer, starting in late July-August (don’t believe the ones saying it’s a spring flowering gentian), it has a decumbent habit (best to have it flowing over a wall or on the rockery slope, if possible) and enjoys a part shaded position. It grows from thickened rhizomes and it is long lived after established.

There are other plants flowering in the garden, of course, most notably Clematis heracleifolia ‘China Purple’, a gentle reminder of the slide towards late August //:-o

Clematis heracleifolia 'China Purple'

Clematis heracleifolia ‘China Purple’

 

Limestone calamint (syn. Calamintha, Satureja)

 Some may have noticed that I’m in love with little plants; I like them even more when they are fragrant!

The Limestone calamint is a dwarf, extremely aromatic species that I really wanted to have in my seed collections and around my rockery. In Ontario, it can be found growing on the rocky shores of Lake Huron, on temporarily moist, calcareous flats (alvars).

Clinopodium arkansanum flowers

Clinopodium arkansanum – Limestone calamint

The little cutie has large blooms for its size, then fruits which remain enclosed in the calyces. The stems take a nice purple colour contrasting nicely with the lavender flowers. Stepping on them (by mistake of course!) will release an aromatic minty wave into the air; also an ID help when not in flower ;)

Unfortunately, it is very hard to say when the seeds are ‘ready’ and had I failed to collect them in the wild during the past couple of years. 

Fortunately, I managed to collect a few this time!

Too cute not to have it!

In preparation of going away for a little while, I looked around today to see who would remain in charge of the garden and the seedlings…The first ones asked found excuses of being busy flowering, setting seeds, or putting up new growth.

So, I had to appoint by force the lord of the garden – Corydalis nobilis. You will hardly find a more reliable, resilient and fair garden fellow. From its corner location it can easily survey the whole garden, including the youngster Cory (from seed) which is flowering for the first time.

Corydalis nobilis

Corydalis nobilis

I read somewhere (most probably in an AGS Journal) about an old, neglected garden where C. nobilis had taken hold of and was growing everywhere like a weed. It can maybe happen in time; say 30 years from now on.
Sounds like a good plan…

And a few May pictures: new and older plants establishing together, Aquilegia canadensis- short form in the sun-rockery (in the making), and… lots of seedlings :) On to the seed adventures at full steam!
