The latest species added to the Seeds List: Eryngium giganteum, better known as Miss Willmott’s ghost (this is the common name, NOT a cultivar name).
A spectacular species for a sunny, well drained garden spot, which doesn’t need much presentation. The seeds require a period of cold/moist stratification in order to germinate well.

With this in mind, and after exchanging emails with people who bought seeds this fall, I think it is a good occasion to draw attention to the Germination page  which I don’t think it is used to its full extent.
Take some time before sowing and browse the various links. There is a wealth of info about when and how to sow, all from personal, practical experience (beware copy/paste info you find on many websites, all ‘sounding’ the same).

For those in zone 6 and below, at this time I recommend to follow the advice from “Practical considerations for sowing in late fall –winter” (I changed the title from “sowing in the winter”).
True, it is not winter yet, but in colder climates the temperatures remain below 10C during the day now and the night temperatures often dip below 0C. In these conditions, if sown and put outside right away, the seeds cannot imbibe properly for the cold stratification to be effective.

Please have a recap on how to proceed for sowing at this time, including if you wish to provide cold/moist stratification in the fridge:
Practical considerations for sowing in the winter

One more thing, there are just a few moist packed seeds pck. left in the inventory at this point. Hurry up before it gets very cold!
Moist packed seeds

All species with hydrophilic seeds must be purchased and sowed at the right time in order to obtain good germination. Until next, here’s how Hepatica acutiloba seeds look when starting to germinate. We can already start dreaming about spring!

Hepatica acutiloba – white fragrant germination start, Nov. 2020

 

I don’t think I had the chance to show C. occidentalis when it flowered this spring; too many other things were happening in May.

Clematis occidentalis (Purple Clematis, Mountain clematis) is a species native to the US and Canada, usually growing in rocky woodlands, near creeks, talus slopes, tickets, often on calcareous substrates.
It is a variable species with 3 var. recognized by Flora of North America: var. occidentalis (Eastern NA), var. dissecta (confined to central Washington) and var. grosseserata (Western NA).

Plants from the Eastern N America belong to Clematis occidentalis var. occidentalis. It is rare that one can stumble upon them in the wild, being scarce in most locations; actually, it is considered an endangered species in a few US States.
It is a trailing or climbing vine on nearby plants/tree trunks, up to 2 m in length with 3-parted leaves, coarsely crenate and/or lobed. The bell shaped flowers are large (up to 6 cm long) and can be reddish-violet to pink-purple.

In the garden, for a natural look, let it scramble on a nearby plant (a shrub preferably) or even better, over stone walls and boulders. The large flowers appear in the spring (May in ON) and will surely attract attention!

Clematis occidentalis var. occidentalis – garden cultivated

Clematis occidentalis var. occidentalis; this is a trailing specimen which likes to scramble on the nearby plants; you can also tie up the stems on a small trellis/obelisk.

Also, the shrubby Clematis integrifolia seeds are back in stock! We missed having them to share in the last couple of years.
Clematis integrifolia – blue
Clematis integrifolia – pink group

More and more people are interested in growing various woodland native species this fall which is very encouraging.
Asarum canadense  seeds have been packed for the last 5-6 orders, so even if it is familiar plant I will make a short portrait; more on few other tough plants in the next post. The aim now is to dispatch the orders as fast as possible.

 There are not enough words for praising our native ginger and I am happy that this year there are more seeds to share. Not only is a beautiful species with fuzzy leaves starting to emerge in early spring and purple flowers, it also very useful as a groundcover in tough locations.

The pictures below were taken in my garden two year ago and this week. The plants grow in dry part/shade on a dry slope under a large spruce and were started in fiber pots 4 years ago, then planted in situ in the fall of their first year. Asarum seedlings are growing very fast.

Not only they cover an area where growing something else would be quite impossible, being a rhizomatous species also stabilizes the ground and prevent the soil from washing down. There is also Maianthemum stellatum, looking a bit ratty at this time and few other species.

The wild ginger is one of the easiest species to grow from the moist packed seeds category. You can even sow the seeds ‘in situ’.
I think would be useful to read a recap for: how to start the moist packed seeds and pay attention to the ‘space saving method’; it is the most easiest and practical way to grow a wide range of woodland native species in our climate with cold winters.
Also worth to read (again) about how to:  Grow Caulophyllum thalictroides from seeds – the easy way.

Thank you all and get sowing – You can do it!

 

 

Gillenia trifoliata (syn. Porteranthus trifoliatus), Bowman’s root, Indian physic

The Bowman’s root is yet another North American native species (S. Ontario and various US states) which deserves more attention. Offered by local garden centers on occasion, it is possible to pass unnoticed if not caught in its full splendor.
Some people are already taking advantage of the available seeds, so it is a good time to talk again about it.

The Bowman’s root is a cold hardy perennial which remains in a tight clump and will grow to 1.20+ m depending on the location; in rainy summers it may need staking. Any partly shaded spot in the garden would lighten up in June when Bowman’s root is flowering in profusion! The white/pinkish flowers with red calyces are distinct and barely disclose the plant affiliation with the Rose family (Rosaceae).

Gillenia trifoliata, syn. Porteranthus trifoliatus

Unfortunately, not all flowers are pollinated and usually the seeds are in limited quantity; the dry capsules mature and split open somewhere in September. Good news is that it is not a difficult species to germinate and grow from seeds.
The germination advice given in the shop: sown in late fall/early winter (cold/moist stratification).

Gillenia trifoliata garden grown with fall color

The deep green, healthy foliage will turn an exceptional bronze-reddish/or yellow color in the fall. What more can we ask from the Bowman’s root? 

Its common names derive from the former medicinal uses of the dry root (laxative, emetic), although they were more often referring to another species, Gillenia stipulata (also called American ipecac).
Other traditional medicinal uses of Gillenia root include: indigestion, colds, asthma and hepatitis. In principle, it was common in ‘cure-all’ elixirs sold by the traveling medicine salesmen in 19th-century America.

 

Parnassia glauca – fen grass of Parnassus, Bog star, American grass of Parnassus

September is always signaled by Parnassia glauca flowers. This species can be found growing in fens, wetland edges and floodplains, on calcareous substrates in NE US and SE Canada.
Despite the name and wild habitat preference, it can be easily grown in the garden in a full/part sun location in a moist enough location, which means, a spot where watering is done at least during very dry spells. Otherwise, during spring and fall there is usually plenty of rain to keep the soil saturated in many parts of Canada.

Parnassia glauca growing in the garden with good companions: Lobelia cardinalis, Iris versicolor, Viola nephrophylla, Sisyrinchium mucronatum

There are many other species of Parnassia in N America, Europe and Asia; the genus name is thought to refer to Mount Parnassus in Greece.
All have very interesting flowers at a closer look because of the 5 sterile stamens, which can have 3 or more branches that display yellow glands at their ends looking like drops of ‘nectar’. It is not nectar, just a way the plant tricks pollinators, which are also guided by the veins on the petals.

Parnassia glauca flower close-up; notice the sterile stamens with 3 branches

For growing Parnassia from seeds, the sowing is best done in late fall with the cold/moist stratification provided over the winter.
One can also try to cast the fine seeds ‘in situ’ in a moist area and hope for the best (cover lightly with sand/fine gravel to prevent them from being blown away).

One of the many new seeds offerings this year, Trillium luteum (Yellow trillium, wax trillium) is a species that belongs to the sessile group. A native of South Eastern US, it has beautifully marbled foliage and light yellow flowers with a pleasant lemony fragrance – which is also an easy character to distinguish it from T. sessile, which is very similar morphologically.

My favorite shade spot in the garden in May is where the yellow Trillium’s slender flowers are effortlessly mingling with Primula sieboldii, Paris quadrifolia and Epimedum stellulatum. This species doesn’t grow wild in Canada or Ontario, which makes it an even more precious plant to have and enjoy in our gardens.

By contrast with T. grandiflorum and T. erectum, the petals are long lasting and the plants seem to remain in flower a long time after pollination. Likewise, the fruits take a long time to ripen; the last ones were collected yesterday.
I was able to check the germination with the few seeds produced in the past years and the germination is reliable in the first spring (a slightly warm cycle followed by a cold period/winter). The first flowers should appear in the fourth year.

Trillium luteum moist packed seeds

 

Although work is still ‘in progress’, most of the species available up to date have been posted on the Seeds List and diligent people have already started their fall shopping.
It is time to advise all interested to do the same; due to the extreme drought in the region, many species will be in limited quantities this year, even those which usually come in bigger quantities. Some species are restricted to 1 pck./order, at least for the beginning of the season.

A second wave will come in late Sept/October. I’m not talking about Covid, we are all tired to hear about it. There are species still in flower or at the end of flowering and for those the seeds will be ripening late.

Keep in mind that mail delivery is slower than usual, although not too bad lately; we have to give Canada Post and all other postal services around the world some credit. Like everyone else, they have had a hard time adjusting to new rules and regulations.

Get excited this fall – grow some plants from seeds and help biodiversity thrive in your garden. Purchase whatever you are interested in and keep the seeds packets handy – sow the cold germinators in late fall and the warm germinators in early spring.
The moist packed seeds, seeds with warm/cold germination pattern and the peony species need to be sown asap.

New to growing from seeds? Have a look first at the Germination page, read a few postings there, take a deep breath, read some more and after that decide what’s good for you.

For all newcomers to this blog/website: Welcome! I hope you enjoy the various writings about plants & germination. Keep in mind that using the Search tab will give you access to everything written on a certain subject.

This is also the start of a series of plant portraits, featuring species from the current SEEDS LIST.

 Polygala paucifolia, aka fringed polygala, gaywings

Fringe polygala is a native species of North America deciduous and mixed forests, with a low growing habit; a perfect plant for a moist/shaded spot in the rockery or at the edge of the woodland garden. If flowers in May, sometimes overlapping with Trillium grandiflorum. The flowers are large, deep pink with wing-like sepals and petals joined at the tip and ended with a frilly crest. Read more, including how to germinate and grow it & plant companions on the product page: Polygala paucifolia. 

A show-stopper when flowering, to say the least! Although a most desirable species, it is extremely hard to catch the seeds at the proper time, like the case with all Polygala species. I am always pleased to be able to offer and share seeds of such species rarely seen in cultivation just because lack of seeds. This year there are more seeds than usual – Enjoy :)

Polygala paucifolia in habitat in May, SW Ontario

Goldenseal (Hydrastis canadensis L – Ranunculaceae) is a woodland species growing only in Southeastern Canada and Eastern US.            

It is known under many other common names: yellow puccoon, eyebalm, eyeroot, Indian paint, wild turmeric, ground raspberry, which can often be traced back to the Native American uses as a medicinal plant. The Cherokee and other Indigenous tribes used the roots of this plant as an antiseptic for inflammations, general tonic, to treat skin problems, and as an eyewash.
Also a golden-yellow dye was produced from the roots (yellow rhizomes), hence the common name ‘Indian dye’.

It was just a matter of time for the European settlers to start using it in a similar fashion. Somehow the popularity of the species grew exponential during early 1990s, and the demand for goldenseal increased tremendously, which of course, lead to the over-harvesting of plants in the wild.

Considered rare and/or endangered, with protection legislation in place forbidding harvesting from the wild, the loss of natural habitat is nowadays adding to the conservation challenges of this species.

Personally I wanted to cultivate it not for medicinal purposes, but as part of the woodland plant community, together with Trilliums, Uvularia, Jeffersonia… and so on.
Goldenseal is presumed to be growing in the some locations in Southern Ontario, but it is elusive and I have never encountered it in the wild.

I am happy to be able to share a few seeds from my garden grown plants (raised from seeds) hoping that more people will offer it a refuge in their woodland gardens. With large maple-like leaves, white flowers and ‘strawberry’ looking fruits, it is a beautiful plant!

Propagation from seeds:

The seeds are hydrophilic and have to be sown right away after being removed from the fruits or moist packed for sowing at a later date.

For best results they have to undergo the natural variation in temperature from our temperate climate: warm (late summer) – slightly warm/cold (fall) – cold (winter). The seedlings will appear somewhere in May, almost at the same time with the adult plants emerging from the ground.
One option is to sow the seeds asap and keep the pots outdoors (cold frame or snow covered in the winter).

For those interested in a more ‘controlled’ germination, I will outline how I grew my plants. For a small lot of seeds maybe it is better to keep a close eye on the process because Hydrastis seeds present a peculiar phenomenon: the embryos start growing in late fall up to the point that the seed coats split to reveal the endosperm. This is due to the embryo growth and can be already noticed in December; they gradually continue to enlarge toward the spring, as seen in the pictures.

I mixed the seeds with slightly moist vermiculite and kept them at room temperature until late fall, then somewhat cooler for a couple of weeks, and then placed them in the fridge to simulate the winter (+/-4C).  The moisture must be checked regularly.

The seeds were sowed in pots after I noticed the first roots starting to emerge (see picture above – late March/April) and the pots placed outdoors in a shaded cold frame (beware the critters, late freeze, heavy rains; a garage is also a good option too since light is not necessary for a while); keep moist, but do not over water (the seeds will rot easily at this stage). The seedlings will appear sometime in May. In the first two years the growth is slow like in all other rhizomatous species and best to grow them in the sowing pot; the first flowers are to be expected in the third year.

Head to the Seeds List, or click here for the direct link to Hydrastis seeds. Only propagation, especially from seeds, truly leads to plant species conservation.                                                                    

*Botanically speaking, Hydrastis is a bit of a controversial genus within the family Ranunculaceae. It was moved to Berberidaceae due to its similarities with Podophyllum and Diphylleia; returned to Ranunculaceae due to its strong resemblance to Glaucidium; placed in its own family – Hydrastaceae, and then finally, returned back to Ranunculaceae.

Its most closely related species is Glaucidium! (which has been awarded its own family in the end). For now Flora of North America places Hydrastis canadensis in the Ranunculaceae.

 

 

Aristolochia (Dutchman’s pipe) hardy species are not often seen cultivated in the gardens. It is a pity since they are quite interesting.
I wrote before that serepindity made it to grow successfully from seeds two such species: Aristolochia iberica and Aristolochia steupii, both hailing from the Caucasus and surrounding regions.

They are both deciduous, trailing vines of deciduous forests, short in stature though, with ‘pipe-like’ typical flowers (hence the generic name Dutchman’s pipe) along upright leafy stems produced in late spring. The flowers are not large, but they are so unusual they make you want looking at them again, and again…The flowers have hairs which will guide and shortly trap insects, but this doesn’t mean they are carnivorous. The pollinators find their way out after performing the ‘required’ task.

Aristolochia iberica: mature capsule showing the seeds. The seeds germinate best when sown fresh or moist packed

The fruits are egg-shaped, hard capsules which will split and release the seeds on short notice. The seeds bear resemblance to those of other species from the family, like Asarum and Saruma. Like ways, their seeds also require a slightly warm/cold cycle for proper germination; if they get very dry the germination rate is greatly reduced.

Another hardy Dutchman’s pipe is our native Aristolochia durior, which grows tall and needs a support or can ‘hang on’ to a nearby tree. I still have to add this one to the garden.

Meanwhile, even if the spring has been cold and capricious, Aristolochia iberica has produced a few capsules &  good seeds.
Those who want to grow something cool, that almost no one else has, give it a try. Show it off to your garden friends as a ‘rarity’ :)

The seeds will become available on Friday, together with few other moist packed seeds.

They are species for the woodland garden, part sun/shade works best (morning sun), in locations with good, rich substrate where you would water during dry spells. They can be good companions for: Saruma henryi, Asarum, Hepatica acutiloba, evergreen Epimediums, Podophyllum, Helleborus, to mention the few that are in my garden bed; also Arisaema ssp. Uvularia, Trilliums, Hydrastis and so on….
Hold your breath because Hydrastis canadensis seeds will also be available soon!

*Although Aristolochia species have been employed for medicinal purpose to treat various ailments, due to the mutagenic properties of the aristolochic acid (found in all plants of this family), today it is advised not to use any preparations based on Aristolochia species.

and Trillium seeds

It is official – the first colorful fruit of the season belongs to Hydrastis canadensis! None of the others already collected can pass as being colorful.

Hydrastis canadensis (Goldenseal) ripen fruit in mid-July, 2020

By the way, seeds of Trillium grandiflorum are in stock, and so are seeds of a light pink form of Sanguinaria canadensis.


Other species benefiting from summer sowing that were recently uploaded in the inventory: Helleborus foetidus and Lilium washingtonianum.

 

 

Hepatica seeds offerings

All the available Hepatica seeds are now in stock: Hepatica category. The sold out forms have been archived and can be found using the Search tab.

I am very happy that this year I managed to collect more Hepatica americana seeds; last spring due to a rainy and cold spring there were just few seeds available. Hepatica americana #1, #2, the bicolor form and the ‘Spring Dawn’ are all delightful!
There is also a new H. acutiloba fragrant! Maybe few of the seedlings will inherit this trait.

 

Following an email from a client regarding the warm period mentioned on the Germination page, I need to make a clarification. It seems that ‘warm’ can be misunderstood. It is a term broadly used for all species which need to be sown in late spring/summer in order to germinate properly.

Those reading with attention on the germination page would have also noticed this: “It has been shown that the embryos will start growing rapidly at the end of summer when the day/night temperatures start to decline.”

So, actually nothing is happening until toward the end of the summer, when with the falling of temperatures the embryos start growing. For all living in the Northern Hemisphere, ‘warm’ simply means: keep the sowing pots outdoors, in a shaded place, and let them follow the natural variations in temperature until winter arrives (keep the pots out of heavy rains, this year seems to be crazy; a shaded spot along the house under eaves, under a patio table, underneath a large shrub…..).

The ‘warm’ period would constitute a problem only for those in the Southern Hemisphere, who currently experience winter.

Advice for those thinking of growing Hepatica for the first time:
Please consider starting with H. acutiloba- pastel mix or any other H. acutiloba.

They usually germinate in the first spring (if instructions are followed), the seedlings are vigorous and
prove to be quite adaptable, including in the garden (H. acutiloba pastel mix seedlings in the featured image).

Hepatica acutiloba ‘Purple Star’ seedlings of last year

Hepatica americana it is a bit more finicky, and some seeds will only germinate in the second year after sowing, regardless that they are moist packed and sown right away.

Please review the Checklist for growing Hepatica from seeds, before purchasing seeds with unrealistic expectations (they may not germinate in the first spring after sowing and it will take 3-4 years until producing the first flower).

As soon as the rains allow, small bags will be placed to catch the Hepatica seeds; for both H. americana and H. acutiloba. I mentioned before that catching the seeds is not an easy task. This year the flowering show was partially missed and we cannot be sure about the seeds until later. I will show a few H. americana plants that I have my eyes on:

Hepatica americana #1
I gave it this ‘name’ a few years ago and in a way it remains my favorite. It is a large specimen, reliable flowering (seeds germinating in the first spring) with violet/blue flowers with a narrow white edging.

H. americana ‘Spring Dawn’
An exciting find with larger than usual flowers with multipetal tendency and also gorgeous foliage. It is a mesmerizing form of H. americana but I don’t know yet if it would come true from seeds.

Few forms with pure, white flowers are also marked for collecting.


A bicolor specimen shown below it would be a first time offering. As well, seeds from a small isolated group of plants with white flowers brushed with pink, they should come true from seeds – a seedling in the featured picture.

Hepatica americana bicolor

Maybe also few seeds from a white form and white/lavender forms with multipetal tendency.

Available seeds will be posted in the shop (in 2-3 few weeks) and announcement will be made here and on FB page (those interested please subscribe to one of them).
Last year extremely cold and rainy spring made it for a disastrous seeds setting so I really hope this season will be better. Fingers crossed!

The checklist posted for H. acutiloba also applies for growing Hepatica americana from seeds.

 

 

What else better on a cold Friday than to look at nice Hepatica acutiloba pictures? This spring the flowering show was partially missed, but there are plenty of pictures from previous years. What forms will be available on the shop is hard to say until the seeds start to form. We can only hope that most will have a good seeds set.

Again, collecting Hepatica seeds is not an easy task. Especially in the wild it requires repeated trips and bagging (this must also be done in the garden) in order to catch the rapidly dispersing seeds.

I would very much like everyone to be successful in growing these beautiful plants. Truth is though, that not everyone has enough patience (and/or skills) to grow from seeds species that require 3+ years to reach a modest flowering stage. So, I put together a checklist.
Checklist for growing Hepatica from seeds; you have to mark OK for all in order to consider growing Hepatica from seeds.
– purchase the seeds preferably as soon as they become available.
– sow the seeds as soon as they arrive, keep the pots under natural conditions in a part-shaded location and water as necessary.
– be prepared to wait until the second spring for germination; i.e. take care one more year of “empty looking” pots.
– transplant and take care of small seedlings.
– wait 2-3 more years to see the first flowers.
– all of the above, while continuing to take care of the plants/pots (they can be also ‘planted’ in the ground/large container)
– all in all, 3-4 years are necessary until able to enjoy the first flowers.

More details on Hepatica page, also Transplanting and caring for Hepatica seedlings, plus see the linked posts below.
Again, there will be an announcement with more details when seeds become available (late May-early June).

 

Today, I continue to record the cultivation of goldenseal, Hydrastis canadensis, in my garden. A reminder that this is an endangered species in its wild habitat! Last year one plant even produced a small fruit and what to do with few seeds? I sowed them of course; now they are starting to germinate, on the same time the adult plants are emerging from the ground.

The beautiful sight of Hydrastis canadensis emerging from the ground yesterday, May 4th 2020

Especially when growing native species it is important to work in sync with nature in your garden. This is also a good occasion to let you know that there is a wealth of good gardening eBooks on sale until May 21.

Those interested, please see the link below for the Earth Day Special on ALL gardening eBooks!

A brief garden ‘woodland’ walk to see various species that were basking under the sun a couple of days ago. Again, trying to use locations in the garden that reproduce the native habitat is the key to happiness.
For most parts this means deciduous woods which allow plenty of sun in early to mid -spring and again in the fall. Combined deciduous/coniferous woods allow less light and can also be dryer (except on bottom lands and river valleys).

Of course that some species are more adaptable than others and having seedlings you can try them in various locations to see how they react.
Asarum canadense, the wild ginger, is one of the most easy going species that can be used as a groundcover. I caught it in the act of flowering in a sunny position, while in more shaded area is still in bud. The second picture shows the success I had establishing young plants grown from seeds on a dry slope (also shoots of Maianthemum stellatum showing up).


Anemonella thalictroides  (syn. Thalictrum thalictroides), rue anemone, is usually found on slightly moist locations. It is very easy to grow from fresh or moist packed seeds – pictured here are 3 years old flowering plants.

Another easy going, spreading by self-sowing is Hydrophyllum virginianum, Virginia waterleaf. It can even grow close to old tree trunks (hint for dry shade resistance!). A most loved species by the bees and bumblebees, so a few plants are a must (young seedlings can be easily removed if not desired).

The spring beauty, Claytonia virginica always loves to be close to the trees. A few left in my garden (squirrels love to dig the corms) and a nice patch flowering in the woodlands last year. The woods are still out of reach and seed collecting remains a question mark for now.

 I will finish for today with these Prosartes lanuginosa seedlings, which are grown in a pot buried in the ground. I have shown this easy method to grow all woodland species from seeds a few times and I repeat it again for all those who recently purchased Caulophyllum thalictroides seeds ;)

Until next…

 

In the last few days I’ve been ‘circling around’ a garden bed which due to the natural land configuration remains temporarily wet, with gradients of wetness and sun to part/sun exposure.
With the warming up I will start adding more species to this area. So let’s see a few native species suitable for such a location. When growing native species (and not only) it is very important to choose a garden spot that best imitates their native habitat.

Iris versicolor (Northern blue flag) is more than happy in such a location; the wetter, the better. Also, a small clump of Iris hookeri will be moved closer hoping for a better flowering. I plan to also try in this location a division of our beautiful dwarf lake Iris, Iris lacustris, which is currently in a drier spot.

Sisyrinchium mucronatum, the slender blue–eyed grass, it is another resident; easy to grow and its fine texture combines beautifully with the Iris leaves.
Parnassia glauca (Marsh grass of Parnassus); any slightly moist place shouldn’t be without a Parnassia! This species gets quite robust after a few years and may even reseed in place. And what a wet area would be without water avens, Geum rivale?

A bunch of Zigadenus elegans (Mountain death camass) seedlings planted last fall are just coming up. Also, speaking about seedlings, a pot of Lilium philadelphicum (wood lily) awaits the spring planting rush to begin.
One can find this native Lilium in various habitats, including (moist) woodland edges, but I’ve also seen beautiful specimens growing in wet ditches and I will try it this way.

There are many more other native species that I will gradually add: Castilleja coccinea and Lobelia cardinalis (seeds to be sown ‘in situ’ by fall). Asclepias incarnata is a must, as are Lobelia spicata and Chelone obliqua if the space allows (to mention just a few…).
Grasses and sedges speaking, there is a nice Deschampsia cespitosa (tuft hair grass) and Carex grayi; I would definitely like to grow more grasses.

Take notes for fall sowing ;) and fingers crossed seeds will be collected.
