Nice dark flowers Véronique!

I add Viola chaerophylloides here - obtained 2019 (as Viola ? chaerophylla)

Viola douglasii

[Véronique Macrelle]

Viola douglasii is very beautiful ..
 I think I have a Viola riviniana rosea spontaneously appeared in the garden, not far from the false 'V. labradorica '(a descendant?). its flowers are very broad, larger than 'V. Labradorian '
here I have trouble with my violets in the pot, it was too hot for them ...
 and I need to restore my camera ...
I am glad to see Viola glabella as I can compare with the leaves of my January planting.

[Gerdk]

Wow! Such a low and compact Viola douglasii. It seems it enjoyed sufficient sunshine!

Gerd,

You have some wonderful Viola species. Jasmin and I especially like Viola somchetica.

I am very pleased that you had success with Viola glabella. 

The Western North American dryland species are very challenging to grow in small containers. I am having success with some of our local dryland species; growing them in large tubs with a soil mixture that imitates their native soil. If you have space and the inclination you might want to give these beauties a try again. Viola tomentosa grows under extremely xeric conditions. In their native habitat, the solar radiation is very intense (actually flux density - intensity is related but something a little different) during the "spring" (June in their native habitat) and summer. On a clear day solar radiation peaks at over 1,000 Wm^-2. The change in the Bowen ratio over the spring to summer/autumn season gives one a good idea of the change in sensible heat/latent heat fluxs that occur and the impact this has on the plant physiology.

We are still in lockdown/habor-in-place mode, but there is plenty to keep me busy.

Viola douglasii

Fantastic Grown in a pot?
I have young seedlings, don't know if I'll be able to see them flowering.

[Steve Garvie]

Thanks Gabriela.
Yes it’s growing in a deep clay pot. The image was taken in such a way as to hide the pot.

Thank you Robert for these detailed instructions - we just expierence an unsual spell of sunny days and it is easily visible how some violets react - I am aware that sufficient light is an important factor in cultivation. But unfortunately temperatures here do not allow to cultivate most of the western (US) violets outside und there is also a need to prevent the plants against too excess moisture. This requires a substantial additional effort (cultivation under glass, artificial light, heating).
I am not able to pay attention to all the aspects mentioned. So I will continue to figure out which species tolerate my possibilities. This leads to a restriction of the number of species which I will be able to cultivate for longer. But as a gardener I will continue to try and try again - Der Weg ist das Ziel - the journey is the reward!

Like you (and all our  neighboring countries)  we experience  the stay at home mode.

Thanks Steve, this would also be a good option for me if not so cold in the winter here. I will look into a weather/cold resistant containers that are on the market now.

Viola brevistipulata hidakana

some violets

1. Originally planted as Viola hispida but since then it used numerous opportunities to hybridize
2. + 3. Viola rubella from Chile
4. Outstanding lavender coloured Viola epipsila
