Now that the Hepatica seeds are all safe and moist and Claytonia capsules are making popping sounds from the paper bags :) we can enjoy a woodland walk.

As the Trillium grandiflorum is coming to an end other species start flowering. The
mayapples (Podophyllum peltatum), Trientalis borealis, Aralia nudicaulis, Aquilegia canadensis, Maianthemum canadensis, Maianthemum stellatum, Clintonia borealis and all others are looking very happy after the rainy spring season. Considering the dryness of the last couple of years it is so very pleasant to see the woods looking green, lush and happy! Follow the links to read more about them or just enjoy the pictures.

Last year there was only one capsule with few seeds on a Trillium luteum. Nothing else to do but to sow the few seeds.
Easy germinator after warm/cold cycles; moist at all time of course.

Trillium luteum, not only beautiful also with a fresh lemony fragrance!

Two pictures for today actually (rules are made to be broken right? :)

I want to show this absolutely cool woodland species which flowers for the first time. I grew it from seeds just because someone sent me seeds 5 years ago. I didn’t ask for them, had no idea what the species was and how to germinate it, or if it would grow in my climate.
Nevertheless, I sowed them. And I was patient.

Aristolochia steupii

Yes, it is possible. There are also few P. comosa and P. verticillata germinating now, in the second year after sowing.

Pedicularis atropurpurea

Sanguinaria canadensis: seedlings of last and this year in the same pot = keep your pots for at least 2 years.

Cycles require for germination (moist at all times): W + C with about 50% of seeds with W + C + W (W- warm, C- cold). From a small sample of seeds you may never know, they can germinate all at once or in stages.
The epicotyl dormancy can be simple or double simple.

Sanguinaria canadensis 2 generations seedlings

Simple epicotyl dormancy = emergence of the roots in autumn and emergence of the shoots following spring; a germination pattern common for many species.

 

 

 

 

A short series on the idea that “A picture is worth a thousand words”.

Glaucidium palmatum: last year seedlings germinated warm and seedlings germinated this spring after the winter cold. It can happen for all seeds to germinate after a cold period (always keep your pots for 2 years).

A couple of days ago I started to prick out Primula seedlings when I realized I should take few pictures first. At this time of the year I don’t always get the chance to show the ‘before’ picture.
Featured image with Primula zambalensis already pricked out (easy, warm germinator).

Primula ruprechtii (cold/moist stratification) and Primula glaucescens (done with GA3/ otherwise cold/moist stratification)

Primula amoena seedlings are still small, will have to grow a bit more (cold/moist for at least 2 months).

Primula amoena

Primulas are also flowering in the garden in all shapes and sizes & colors. It is good to adopt a relaxed attitude when growing Primula from seeds.
They are among the easiest to grow but keep in mind that some species hybridize easily in the garden; also the cultivars may not be stable (for ex. Primula ‘Sunset Shades’). But they are all wonderful.
Aquilegia nigricans just starts flowering – a reminder that early flowering columbines always make for a good combination with the primulas (A. canadensis in flower as well).

It is always a joyful moment to see various species grown from seeds flowering for the first time. No matter if they are common or ‘rare’ species, natives or not, they bring a different feeling than those acquired from a garden center.

Flowering first time from the shaded side of the garden:

Podophyllum hexandrum (syn. Sinopodophyllum)

Podophyllum hexandrum, Himalayan mayapple

Triosteum pinnatifidum, a species grown for its beautiful foliage and fruits; the flowers are not showy but without them we wouldn’t have fruits ;)

Triosteum pinnatifidum

Lathyrus vernus, grown from own wild collected seeds, which adds to the satisfaction!

Other species that flowered for the first time in early spring in the shade were: Helleborus purpurascens and Pachyphragma macrophyllum.

More to come. And let’s not forget the sunny side!

Out in the woods yesterday on a cold, windy day. I knew that the trout lilies (Erythronium americanum) flowers are fading; when it’s happening, the large flowered Trillium (T. grandiflorum) starts to flower – it is a given in our region.
And when the white Trillium is flowering, look up and admire the unfolding buds of Carya ovata (Shagbark hickory); the large, peachy cataphylls are hard to miss. It is another given.
Suddenly, the new, reddish foliage of wild sarsaparilla (Aralia nudicaulis) is all around, together with the yellow bells of Uvularia grandiflora (large flowered bellwort).

Uvularia grandiflora

Everything is interconnected.

Note: due to the cool spring, Claytonia virginica and Hepatica seeds will mature later than usual this season.

 

The germination of various species is slower than usual due to the cold spring we have. Of course the native species are among the first to germinate.
Some were sown because I need more plants: Anemone quinquefolia, Asarum canadense, some to test the germination for older seeds: Dodecatheon hendersonii (2016 seeds) , or first time offered species: Zizia aurea.

For Lilium philadelphicum I wanted to test the germination on smaller than usual seeds we obtained in the last 2 years due to drought conditions. I used the ‘freezing’ method described and it seems – size, it does not matter. All germinated!

Lilium philadelphicum seedlings

In the the featured image: Strophostyles helvola, the Amberique-bean; I found 3 leftover seeds, what else to do with them?

I am not among the people who say that we should grow only native species in our gardens. I think it is extreme and unrealistic. Not all native species are easy to grow and adaptable to garden cultivation. You have to study them first in their wild habitats, understand their needs and determine if these needs can be met in a garden situation. There are many factors involved.

But it is true that everyone can accommodate quite a few of them, and not just because they are hardy and good for pollinators (so are many others), but mainly because they adapt wonderfully in so called ‘difficult locations’ which resemble their native habitat.

To cut a long story short, I was facing a steep slope underneath an old spruce; the soil, or what was left of it, wouldn’t allow digging decent planting holes. The area gets sun in the spring and it becomes more shaded in the summer.
Trying to establish native species on it made sense; entirely. And starting with young plants grown from seeds also made sense: they establish much easier.

This is one part of the area right now: Asarum canadense and Maianthemum stellatum are 3 years old. There are various few smaller seedlings which don’t show and few young Trilliums.  With the backbones in place, I will also directly sow other seeds in late fall; particularly Thalictrum dioicum for its fine texture.

Asarum canadense and Maianthemum stellatum

Lower down, a small patch with Anemone quinquefolia, Hepatica americana – more to be added.

Anemone quinquefolia and Hepatica americana

On the reverse side, there is another small area where water pools temporarily due to a terrain depression and clayish subsoil. I’ve tried a few things which never performed well. Then I switched to Primula mistassinica, Viola nephrophyla, Sisyrinchium montanum, Parnassia, and all is well (the area still ‘under construction’, Viola nephrophylla in the featured image).

It all makes sense.

 

 

A picture with Viola jooi from last week to keep us going through another cold & rainy day.
Viola joy!

Viola jooi, the Transilvanian violet: an acaulescent, limestone loving species, endemic of the Carpathian Mts. (Romania, Ukraine); a new population was also described from NE Serbia
