The waterleafs – to each its place

,

Hydrophyllum virginianum and Hydrophyllum canadense

Among the Crocuses, reticulate Irises, Corydalis and Hepatica in my garden, the young foliage of the waterleafs also appeared last week: H. virginianum (Virginia waterleaf) and H. canadense (Blunt-leaved waterleaf, maple leaf waterleaf).

It makes sense because these species are among the first to carpet the forest floor in eastern North America before the trees leaf out. The foliage in early spring is very attractive with white/silver spots, hence the common name; it will later turn to green.

Hydrophyllum virginianum – early spring foliage

Hydrophyllum canadense

For H. virginianum, soon after the foliage turns green, the helicoidal inflorescences with ciliate calyces start unfolding to reveal the bell shaped flowers with exerted stamens in a wide range of colours from deep lavender to white. Hydrophyllum canadense flowers later and the white flowers remain hidden under the foliage; a pity, they are so pretty!

Equally important to their attractiveness, the waterleafs are considered as plants with ‘Special value to Native bees’ by pollination ecologists because they attract a large number of native bees. In my forest walks I rarely see a H. virginianum which is not foraged by the bumble bees.

They also have been used as medicinal plants and the young leaves/shoots are edible (other common name for H. virginianum = Shawnee salad)

H. virginianum grows in part-shade/shade deciduous forests; Hydrophyllum canadense is more common in flood plains forests and along streams.
Both spread by rhizomes and will form colonies; reason why some call them ‘weedy’. In any case, under dry shade you don’t need to worry for H. virginianum.
On the other hand, if a low maintenance ground cover is desired, in proper conditions they can do the job. Actually the ‘weedy’ H. canadense is listed as extremely rare or threatened in few US states.

To each its place….

Let me ask you a question now– with all the buzz and fuss about the pollinator plants, in how many gardens have you seen waterleafs cultivated ?

For Hydrophyllum spp. germination info please read: Lost in translation
The fruits mature gradually and split up when ripen; they are not among the easiest seeds to collect.

Update on Jeffersonia diphylla germination

,

Short update on Jeffersonia diphylla germination.
I kept a small batch of seeds in the fridge to see if they will start to germinate at cold; some species do it,  others not.

Those who bought seeds should see the first seedlings appearing somewhere in May :)

 Jeffersonia diphylla – germination start in early April at cold; seeds kept moist at all times, warm, then cold (fridge)

 

Hepatica – The queens of the woodlands

,

As soon as I saw the first sign of Hepatica buds movement in the garden and the tiny new seedlings of the year, I felt a sense of urgency to organize all the material I’ve been gathering on Hepatica.
The queens of the woodlands will bring the forest floor to life once again in no time!

Having had other posts published and a lot of pictures I thought it would be easy; more than a week later, I was proven wrong.
I am almost done – this is the big purple button leading to their page :)

The pain and joy of dealing with moist stored seeds

,

When I embarked on my seeds adventures few years ago, I’ve decided that there will be no DOD’s offered by BotanyCa (DOD = dead on delivery).
Sometimes seeds won’t germinate from unforeseen reasons, abnormalities and so on… Offering seeds that you know from the beginning won’t germinate or will germinate in very low percentage is a completely different story.

So, I accept the losses and the fact that there will always be leftover seeds germinated in the Ziploc bags by early spring.
When it comes to seeds, just like in nature, everything is accomplished with a great waste of energy. Yet, I am always sad when the time comes to end their ephemeral life.

Saruma henryi: germinated seeds which cannot be safely shipped anymore

 On the other hand, I imagine the joy of all those who bought moist packed seeds when they start to germinate!

Other species which ALWAYS start to germinate by late February when kept moist are: Asarum ssp,, Claytonia, most Corydalis,  Aconitum, Hepatica, Podophyllum spp., sometimes Maianthemum stellatum and M. canadense.
*If kept dry some of these species may germinate in the second year, in low percentage.
I hope there is be a better understanding now why seeds of these species need to be ordered in early winter!

 

More Comps flowers and apologies

, ,

I knew this it will happen sooner or later and I knew it will be a damn comp – running short on seeds for an order.
Luckily there are many other species that I can make up with for the missing Aster alpinus seeds.

Aster alpinus – good (upper right corner) and bad ‘seeds’

The embarrassing moment put behind, let’s have a look at a few more Comps flowers.

Growing Podophyllum from seeds, including Dysosma and Sinopodophyllum

,

While in the Berberidaceae realm, here’s a post where I outlined as best as possible, the process of growing Podophyllums from seeds from A to Z.

The Chinese Podophyllums (syn. Dysosma), share similar seeds and germination requirements as our native Podophyllum peltatum (mayapple). In all cases, the seeds are enclosed inside fleshy fruits. After the fruits are collected, it is important to extract and clean the seeds right away. This can be a bit unpleasant because the inside containing the seeds is gelatinous (use a sieve and lightly rub the seeds out and rinse, rinse and rinse again).

The sowing must be done right away (Sept./October) or the seeds must be placed in moist vermiculite in Ziploc bags until sowing. The seeds are easy to keep in moist vermiculite as long as were well cleaned; you only have to check the moisture level once in a while (one exception noted for Dysosma aurantiocaule, when the seeds got soft fast, but I had a small lot of seeds and cannot really generalize).

I must emphasize that these seeds are hydrophilic, and using dry seeds to sow, in my opinion, is a complete waste of time.

Dysosma seeds in moist storage

The required cycles for germination are: Light WARM (late fall temperatures)/COLD.

  1. Sowing outside: the time would be early to late fall. Sow as usual in pots/large containers, water and keep them over the winter in a cold frame. Easy done, no worries!

Podophyllum peltatum, Mayapple, seedlings germinated outdoors showing the cotyledon leaves; they will remain at this stage in the first year and do not need pricking out. Later in the season, they become dormant (do not throw away the pots!)

  1. Sowing indoors: usually done in the winter/early spring with seeds that have been kept moist and allowed a light warm/cold period. The cold period can be provided in a cold garage/fridge. It is not advisable to use this method unless enough light can be provided for the growing seedlings (light stand, conservatory).

If someone wants to speed up the process, the Ziploc bags with seeds can be taken out of the fridge around late January/February and kept at room temperature; gradually the seeds will start to germinate and can be potted up one by one and placed under the lights.

Dysosma hybrids (pleiantha x versipellis, syn. Podophyllum pleianthum x versipelle) seedlings

Or, leave the Ziploc in the fridge until all seeds start to germinate towards spring (approx. March/April) – as well, pot them up and provide adequate conditions until they can go outside.

Dysosma hybrid, seeds germinated in the fridge, April 21

In most cases, only cotyledon leaves will be formed, in other cases the true leaves will appear as well. Usually, Podophyllum peltatum will form only cotyledon leaves in the first season, grow for a while and then go dormant; the Chinese ones are variable, most will form a true leaf. When growing from seeds there is always great variability.
Keep the seedlings in a part shaded place, water and feed lightly. At some point in the summer they may go dormant, especially if very hot weather.

All the seedlings which didn’t form a true leaf in the first year, will do it in the second year. Be patient, like with all other species that form a rhizome. In general, 3-4 years are necessary to obtain a good young plant; they will grow really fast after the root system has bulked up.

Podophyllum hexandrum (syn. Synopodophyllum hexandrum)

The difference in this case is that the seeds are not hydrophilic, so they can be kept dry in the fridge for quite a few years. Of course, when sown fresh (fall), they will germinate in the spring.

For dry seeds, a GA3 treatment followed by sowing at room temperature usually will result in rapid germination, and sometimes most seedlings will present the true leaf. 

Podophyllum hexandrum seedling with true leaf

Important for all species: in the first 1-2 years they put lots of energy into forming their radicular system; this translates in the fact that the seedlings need enough space to develop. So, either sow fewer seeds per pot or transplant them in the early stage in individual pots.
I think my pictures show very well what I mean; learn from my mistakes ;) If you sowed to dense and didn’t prick them early, don’t panic; when still dormant (very early spring), shake the soil, untangle the roots gently and repot in a fresh mix in large size pots.

Podophyllum hexandrum one-year seedlings prepared for repotting, notice the variation in size

Again, there is always variation when growing from seeds; we cannot expect all the seeds, even from the same batch, to grow the same: the collection site, mother-plant, ambient factors, all have an influence in germination & growth of the seedlings. This picture with one year old Dysosma plants shows it very well:

I hope this will be helpful for all wanting to grow any Podophyllum/Dysosma species from seeds – Happy Podos growing!

Fridays Seeds and much more about the fuzzy wild bean – Strophostyles

,

I wanted something special for this arctic day and the woolly seeds of Strophostyles helvola are just perfect; I will stress again the woolly :)

Strophostyles helvola coiled pods and seeds

Strophostyles helvola, trailing wild bean (or amberique bean)  is an annual vine native to eastern Canada and the US; the pea-like flowers are light pink/lilac and they form pods very similar with those of Phaseolus vulgaris; the pod coils when it dries up to release 4-8 woolly  seeds.
The stems will trail on other plants, or if not, will inter-twine with each other on the ground, just like Amphicarpaea bracteata does (google images).

This species has had various medicinal uses for the Native Peoples, and there are also indications that the seeds were used as a food source; they were found in a few archeological sites in NA.

Those interested can read more about this in the curriculum of the Advanced Paleoethnobotany Seminar from Washington University: https://pages.wustl.edu/fritz/strophostyles-helvola-l.-elliot

And, while talking wild foods, it’s winter so new ideas are always welcomed – have a look at this article which recommends other edible species found on the coastal habitat (same where Strophostyles can also be found):

What about: amberique-bean humus with cattails au gratin?
Go foraging this year! :))

All Violas in one place

,

To finalize the query about the new Viola I was talking last week, pictures of seeds were taken (more detailed than usual): size, surface, colour, aril size and aspect are all useful characters for identification.

Viola cf. declinata seeds

Unfortunately, not having a term of comparison the identity is still uncertain. So, until I grow a few plants it will be offered as Viola cf. declinata.

While at it, why not see about other Viola spp. seeds? And, of course, why not have a Violaceae page in the Seeds Library? Have a look and notice the subtle differences between Viola renifolia and Viola macloskeyi seeds (these two native species are a bit hard to differentiate).

And how about a Viola category in the seeds shop? :)) On this occasion, I ‘discovered’ I forgot to add the Viola pubescens, as well as Viola jooi seeds to the inventory.

It’s so good to have everything in one place!

Friday’s seed and plant portrait – Hypericum kalmianum

,

Having too many seeds makes it hard to choose which one to show/write about.
I am going the easy way with the last species uploaded to the shop – the Kalm’s St. John’s wort, a (sub)shrub native of the Great Lakes region in Canada and US.

Hypericum kalmianum seeds – Kalm’s St. John’s wort (Fam. Hypericaceae)

Cultivated to some extent, this Hypericum has narrow bluish-green leaves and cheerful, large golden flowers with extruded stamens in late summer; the capsules mature very late.
It is a showy, adaptable plant; evergreen (or partly) and as one can guess after its wild habitat, with excellent cold hardiness. Another attractive feature is the brown/reddish bark which peels off.

Lots of qualities!

Lobelia kalmii

The specific epithet honors Pehr Kalm, one of Linnaeus’ disciples ; an explorer, botanist and naturalist, he traveled to and lived for a while in North America in mid-17th , discovering and writing about plants, animals, insects, Niagara Falls, and in general about the life of American colonies at the time.

Another species that can be found with H. kalmianum, bearing the same name is Lobelia kalmii  shown in the gallery.
Days are short now so you can start to read more about Pehr in the wiki stub and then follow other links: https://en.wikipedia.org/wiki/Pehr_Kalm

Friday’s Seeds and plant portrait – Amsonia hubrichtii

, ,

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 ;)

 

The cranberry

,

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.

Vaccinium macrocarpon habitat

Vaccinium macrocarpon seeds

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!

 

A well done job

Never enough gentians….

In my opinion the bumble bees did a great job with Gentiana andrewsii. There are enough seeds for Canada 150 Celebration sale, and also for the seeds exchanges! :)

Here they go!

Trillium grandiflorum seeds are just beginning to germinate! As well is Paris quadrifolia; I noticed the first signs last Saturday (with my x40 lens).

I snapped a few pictures when I was packing some today; they are advanced enough to be noticeable even if the pictures are not great.

Trillium grandiflorum seeds starting to germinate

 

Paris quadrifolia seeds barely showing the radicle

No matter what someone else says or writes, this is happening every year.

For these species, moist stored seeds kept at warm (room temperature) will always start to germinate around this time (roots only).
From all T. grandiflorum seeds, 70-80% will germinate now (roots) and then show the first leaves in the spring after a period of cold stratification. The rest will need one more warm/cold cycle to go through the same cycle.

Paris quadrifolia seeds were also tested two years ago and at that time they all germinated by November (this year I only got few and were promised to someone).

On short, hurry up if you think about Trillium grandiflorum; right now I can select and send seeds that are just about to germinate (they are enlarged and lighter in colour – see the feature image).

 

 

Friday’s seeds – Mitchella repens

,

I recently collected more partridge berries, together with Lindera benzoin and Prosartes lanuginosa (already shown, click on names).

Mitchella repens presents an interesting fruit, therefore worth a closer look. The red, fleshy, ‘two-eyed’ fruit it is formed after the fusion of the flowers ovaries – the white, fragrant flowers are disposed in pairs.  So, each pair of flowers will form one fruit. Each fruit has a spongy inside (a bit like Gaultheria) and will contain up to 8 seeds.

Mitchella repens fruits and seeds – Partridge berry, twinberry, squaw vine (Fam. Rubiaceae)

Why this perfect, evergreen ground hugging plant is seldom seen cultivated in the gardens remains a mystery to me. It can be easily propagated by cuttings as well.
