Moist packing – what’s that?

, ,

As I was packing seeds today, I thought that maybe some people who never bought or they buy for the first time moist packed seeds may wonder what they would get.

Sometimes I get questions as well, so although I have shown pictures in previous posts, it is good to tell again. There is no secret; seeds that are known to be hydrophilic (to make a long story short – these are seeds which need to be sown right away after collecting or if not, kept moist to preserve their viability), are cleaned from the fruits and stored in slightly moist vermiculite in Ziploc bags. And no, there is no need to spray the seeds with anything chemical.

For shipping, the portion of seeds is placed in smaller bags with a bit of the moist vermiculite (*exception for some AU and NZ orders, when the seeds may be packed with a piece of moist paper towel). These seeds are to be sown right away after receiving.

These small bags are not intended for storing the seeds long term!!! (I know someone tried to do that, that’s why I mention it). If you really want to keep the seeds longer, and /or provide stratification in the fridge instead of sowing, you need to transfer them in larger bags with added moist vermiculite (slightly moist peat works as well).

Very small seeds, like those of Coptis shown in the picture, are easily sown by spreading the content of the bag on top of the potting mix (no need to pick the seeds from the vermiculite). Even larger seeds are better sown this way.

Coptis trifolia moist packed seeds

In case of hydrophilic seeds, if kept dry they will either not germinate at all, or will germinate poorly/over a longer period of time. Keeping them moist and allowed the required cycles that mimic the natural conditions will result most times, in 100% germination in the spring. It is a lot of extra work but worth doing it.

Thank you! – Merci! to all our customers

 

Friday’s Seed – Jeffersonia diphylla

, ,

During a visit to the Aspen Groves Gardens to leave a few of my ‘precious’ seedlings for babysitting, I have also been ‘presented’ with nice, fresh and fat seeds of Jeffersonia diphylla :)

The seeds don’t keep very well in moist storage and I will be trying a new method this year, but you may never know how it goes…I recommend to those who have been waiting for it, to get hold of the seeds right now (orders are accepted until July 12th, then the Shop will be closed till August 10th).

All you need to know is here: https://botanicallyinclined.org/growing-jeffersonia-from-seeds/

Jeffersonia diphylla, Twinleaf; few seeds still attached to the fruit wall.

Jeffersonia diphylla seeds – 1 mm grid

 

And btw, those living in driving distance from Guelph, Ontario – this Saturday, July 8, Aspen Grove Gardens of Robert and Judy Pavlis are open for visiting from 10 am- 4 pm.  Don’t miss the opportunity!

Read more and see pictures here: http://www.robertpavlis.com/aspen-grove-gardens/

 

Note: Besides sowing fresh or moist kept seeds, I emphasize again the requirement for good germination.

Baskin & Baskin have shown that ripe seeds of Jeffersonia diphylla have an underdeveloped embryo. Seeds need high summer temperatures (30˚C) in order for the embryo to develop optimally and reach at least one mm in length before dormancy can be broken by cold stratification. If this requirement is not met, another warm/cold cycle is required by the seeds to germinate.

Breaking the tradition – Medeola virginiana germination

,

More updates on germination requirements

It seems that Medeola virginiana seeds don’t follow the traditional double morphophysiological dormancy (MPD). Unlike most species with this type of dormancy, which require a cold-warm-cold cycle to germinate and produce roots in the warm period (2 years seeds), M. virginiana seeds do not form a root during this time; instead, root and cotyledon emerge at the same time in the second spring after sowing.

Medeola virginiana seedlings; seeds sown fall 2015 – germination spring 2017

Speculations are that this sort of germination pattern may represent a transition towards a type of more complex MPD.
Or is it sorcery involved ? ;-)

OK, the practical meaning of all this: be patient and don’t scratch the pots looking for tiny roots in the first year.

For me: I could keep the seeds in moist storage until the second spring, if I would have that many…

Note: again, we are talking here about sown fresh/moist kept seeds.

Lost in translation – updates on germination requirements

,

Slowly, as I have the chance to try more species myself, and/or find reliable info, I work on making updates for the germination requirements on the Seeds shop. I already mentioned about Sanguinaria canadensis.

It is easy to ‘get lost in translation’ when reading about various types of morphophysiological dormancies, but a short summary for species from temperate regions that require warm/cold cycle for germination will be as follows:

This dormancy breaking requirement is naturally fulfilled by summer (high temperatures) followed by fall (lower warm temperatures) and winter (cold stratification). Note the need of high followed by low(er) warm temperatures.

Because of the collecting/shop logistics and peoples habit of buying seeds in late fall, this means that such species, when sowed in late fall/winter will need the whole next season to undergo these requirements, although otherwise they would not qualify in the ‘2 year germinators’ category.
So it goes: changed from require ‘cold stratification’ to ‘warm – cold stratification’:

Hydrophyllum virginianum
Hydrophyllum canadense
Aralia racemosa
Prosartes lanuginosa (moist packed seeds available this fall I hope)
Ilex verticillata

Hydrophyllum virginianum seedlings, seed sown fall 2015, too late for the warm treatment, germinated this spring (2017)

Prosartes lanuginosa: seeds sown after collecting in early September 2016 – germination right now (I only had about 9 seeds)

Other warm/cold germinators that we already know about and I already posted pictures (many require moist storage): most Corydalis, Allium tricoccum, Asarum canadense and europaeum, Saruma, Anemone quinquefolia and A. nemorosa, Dicentra (D. formosa in the featured image), Thalictrum thalictroides, Jeffersonia, Hepatica….

Simplicity – Geum triflorum

,

Easy to grow in the garden and from seeds, this North American Geum is an absolute a delight!  An unpretentious, care free plant in most locations; sun and good drainage required. Best when planted in large numbers for the ‘smoky’ effect of the feathery seed heads (Prairie Smoke ;) in the summer.

Geum triflorum – Prairie Smoke, Old Man’s wiskers; rosy-red, nodding calyces/flowers, followed by feathery seed heads; the compact, ferny looking foliage will become reddish in the fall.

Propagation from seeds: I did a whole bunch last year – sown in the fall and left outside (cold/moist stratification) and the germination was excellent; I planted the seedlings in the garden by late fall.
The grown up clumps can be easily divided every few years.

Note: Other sources indicate sowing at warm.

Out in the woods – Hepatica

It is that time of year when Hepaticas are flowering in the woods (and in the garden). Scouting in areas with large populations always leads to finding interesting forms!
The Hepatica acutiloba specimens shown below are isolated clumps and there is a good chance that a good proportion of the seedlings to come true to the mother-plants.

Hepatica acutiloba 1 – 2017

Hepatica acutiloba 2 – 2017

As well, this is the first find of a Hepatica americana with true pink flowers

Hepatica americana pink – 2017

Semi-double forms are not that rare as the pink flowered, but still a nice find.

Hepatica americana sd- 2017

The Hepatica shop section will be updated as soon as we’ll be able to tell how the seed forming is going on.

Also Claytonia virginica is in flower and soon Sanguinaria canadensis….a kind reminder that the Pre-orders page is up and running!
Usually there are plenty of Sanguinaria seeds and they keep well in moist storage, but asking for seeds of Claytonia, Erythronium and some of the special forms of Hepatica late in the fall, can only lead to disappointment…

Snowflakes by design: Mitella diphylla

,

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.

From the shady side

As we are approaching the longest night of the year, it seems appropriate to present few species from the shady side. The characteristic rain forest of the area presents itself as an enchanted place with huge ferns, moss clad tree logs and boulders, and lichens of all sorts and shapes. One could easily imagine how handy rain gear would be if visiting in spring or fall!

Growing on a most beautiful mossy outcrop populated by reindeer lichen, Goodyera, hairy Arctostaphylos and ferns, was Plectritis congesta. Some plants were already with seeds, but a few were still flowering and looked very nice in deep pink on the background of moss covered rocks.

Plectritis congesta, the Sea blush (Fam. Caprifoliaceae), is an annual species, very adaptable to growing conditions and quite variable as height and flower colour.

A species abundant in cool and shaded damp places, was the broad-leaved starflowers – Trientalis latifolia (Fam. Myrsinaceae more recently). The species can be easily distinguished by its very broad leaves, which make the pinkish to white flowers look smaller than they really are. As well, Linnaea borealis was frequent in the same microhabitats.

Trientalis latifolia – all populations found had pink to deep pink flowers, some also presenting extra petals

There would be much more to say and show, but Christmas time is close, so I will end this trip with a few lichen images, so specific for the coastal rainy forest habitats (there are also species growing in full sun locations). Species shown here belong to the Cladonia and Cladina genera (reindeer lichens), but since I’m not a lichen specialist, I will abstain from assigning species names. We can just admire their most beautiful, intricate and delicate patterns.

And a Merry Christmas to all!

 

Plants of the Canadian West Coast – II

,

More snow is on the way for us (and bitter cold), but we are hiking on the Sooke Coast trail where there are many flowers ;) Enjoy and more to come…

As I mentioned in part 1, Sedum spathulifolium seems to enjoy the company of many other species: Triteleia/Brodiaea, Allium cernuum, Heuchera micrantha and Pentagramma, to note just a few. The contrast of its bluish rosettes with the violet flowers of Triteleia laxa was particularly exquisite.

Brodiaea coronaria

Triteleia laxa Brodiaea coronaria – corrected thanks to a SRGC forumist, grows from a small, edible corm (Fam. Asparagaceae) and flowers usually after the foliage dies back. Flowers can be light blue to violet, rarely white; especially attractive when growing in groups, with the flowers showing up among the golden, dry foliage.

Another Triteleia species encountered was Triteleia hyacinthina (fool’s onion). The plant can be variable in height (10-40 cm) and has compact umbels of white flowers (sometimes having bluish tints) with green midribs. I don’t know really know if to call this one Brodiaea…

Triteleia hyacinthina

Triteleia hyacinthina close-up

Allium cernuum, the nodding onion, was also found growing nearby and looked very attractive when drooping gracefully over a rock ledge.

Allium cernuum

Taking pictures of Triteleia, I noticed something glittering in the sun down the slope and approaching to see better, I noticed the goldback fern – Pentagramma triangularis. This lovely small sized fern can remain evergreen throughout the year when enough moisture is available.  In full sun and dry conditions, as I found it, it will curl its fronds and reveal the golden spores. I know the picture cannot show the reality of the ‘golden glitter’, but it’s true. What a great little fern for the rock garden!

Pentagramma triangularis – Goldback fern on Sooke Coast Trail

Meandering around beach pockets, the hiking trail enters sometimes into the forest (there is also an option to return through the woods to the trailhead). Majestic Douglas, Tsuga, Sitka spruce and Thuja plicata will accompany the path; it’s only after the bark that you can tell which one is which. A spectacular shrub encountered in large numbers as an understory, was the salal, Gaultheria shallon (Fam. Ericaceae).

Gaultheria shallon – Salal

This is an evergreen shrub, 1,5 m to 3 m tall, which can form very dense thickets. The leathery, thick leaves and the racemes of urn-shaped, white to pink flowers make it for a very handsome shrub. Fruits are purplish-black berries that are said to be sweetish and flavourful. Salal berries were a staple food for the NW coastal First Nations, who use to eat them preserved in oolichan (bear fat – correction thanks to a  sharp eye, oolichan or smelt is a fish – see end of the post for more info), pounded and dried into cakes (kept in woven baskets over the winter). There is also mention of mixing the fruits with salmon eggs to obtain a sweetish dish…

Gaultheria shallon

 

Excerpt
read more here – Eulachon, Oolichan, Candlefish, Hooligan 

“To Native Americans, the return of the eulachon meant the beginning of spring and a renewed food supply, literally saving lives and earning them the name “salvation fish” or “savour fish.”  They were the first fish to arrive in the river after a long cold winter when most of their stored food supplies had been depleted.   Unlike other fish oils, eulachon lipids are solid at room temperature, with the color and consistency of butter.  These fish are almost 20 percent oil by weight, allowing a fine grease to be rendered from their bodies and creating a high-energy food source that could easily be transported and traded with other tribes farther inland.”

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

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 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.

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.

Test –Viola nephrophylla

,

A test post to see if the subscribers notification glitch, kindly ‘provided’ by the last Jetpack update has been fixed.

Yesterday, I found the little, large flowered Viola nephrophylla flowering – autumn denial or maybe just a test as well?

viola-nephrophylla1

Viola nephrophylla – Northern bog violet

This North American Viola, commonly called Northern bog violet, not only that is very easy to grow but also adapts splendid to garden cultivation, in a moist place; you don’t really need to have a bog.

Cuteness alert – Clinopodium arkansanum

,

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!

American lotus

,

Nelumbo lutea

A bit of a surprise – there is a lotus that grows wild in Ontario! It is found only towards the extreme southern part of the province, and according to wiki it was introduced in various regions by the Native Americans who carried it along with them as a food source (the tuber). It is fully hardy to zone 5, as long as the water is deep enough and the roots won’t freeze.

Nelumbo lutea foliage

In warmer regions it is quite a colonizer and also called water-chinquapin. Supposedly, it is the largest native wildflower, at least in wetlands, its leaves reaching more than 60 cm in diameter! The seeds are surely among the largest too!

Nelumbo lutea seeds

Nelumbo lutea seeds – 1 mm grid

I cannot abstain from trying to germinate a couple of these seeds. They need to be scarified or nicked and should germinate in water after +/- 2 weeks. For scarification you can use sandpaper or, for large seeds like these, a file. When scarifying the question is always – how much of the seed coat should be removed? It varies from species to species but the general rule is: ‘less is more’. When done well, the seeds will slightly enlarge in a few days; if not, they can be easily scarified some more.

I am sure everyone knows that lotus seeds can remain viable for several decades, given their extremely hard seed coats, so most probably I didn’t file them enough. My short nails, have gotten even shorter.

UPDATE – July 20, the seedlings were planted :)

Catch me if you can!

It is well known that over millions of years plants have evolved and adapted their seeds dispersal strategies to ensure that their progeny reaches new places where hopefully they will be able to germinate, thrive, and continue the cycle of life.

Yet, every time I witness their ingenious ways of doing so, I wonder and cannot help but express my admiration: explosive capsules, seeds with ‘wings’ and other flying ‘apparatuses’, floating devices, ‘bait’ for ants, rewards for animals, and so on…

A couple of days ago, I captured by chance a Stylophorum diphyllum capsule already opened, with the seeds rolling down:

Distracted by the Arisaemas showing up, I almost missed the Helleborus ‘Cherry Blossom’! It’s not enough that the follicles are opening without warning, they also do it gradually.

Then, in the woods I managed to collect a few Thalictrum thalictroides seeds (formerly Anemonella); they are still green when ripe, but only a small touch and in an instant the achene cluster will disintegrate between your fingers.

There are many other notorious ‘seed defectors’ like: Corydalis, Epimedium, Anemone quinquefolia, Hepatica, Spigelia, Viola spp.…to name just a few.

Catch them if you can :)

 

Hot Corydalis

,

It was hot today (felt like 38C!) and I noticed the delicate Rock harlequin (Capnoides sempervirens) flowering. I must say, the colours are just perfect to describe such a fiery day!

Capnoides sempervirens

Capnoides sempervirens

It was sown successively from late winter to spring and older seedlings are the first to start flowering now; a few are still growing up. The key to success with this biennial Corydalis (and also some of the perennials) is to plant it in different spots of the garden and, fingers crossed it will reseed and take care of itself afterwards.

If someone noticed, I call it first Corydalis and then I wrote it as Capnoides. Corydalis spp. used to bear the same name. And then, as it happens, few names have changed. I always hesitate: should I write the older name or the ‘new’ one. Many people will always call them Corydalis (and so do I, privately ;)

To resolve the situation, I made a new category for the seeds shop – Corydalis & all, where they can live happily together…

A perfect – woodland – day

If I leave aside the heat, the endless road constructions/detours and the million mosquitos hungrily awaiting into the woods, yesterday was quite a perfect day. The first seeds of the season were collected and a new, nice Trientalis borealis population has been found.

Really perfect; only that I had to keep reciting Issa’s haiku.

What good luck!
Bitten by
this year's mosquitoes too.
