Alex O'Sullivan, from RBGE is  lucky enough to be  spending a week at the  Gothenburg Botanic Garden - he  posted   these  photos  on Twitter .... 

"A little stunner loving crevices to bore roots into amongst the tufa landscape. This is Viola pachyrrhiza, having seen a much whiter and purpler form in the past, I have to say this trump's it with green and cream petals with a purple tongue".

Indeed - a superb form! I cultivate one with quite smaller flowers.

it is beautiful ... remarkable.

I imagine that grown in a tuff like that, it must be watered every day?

here in my culture, I fight with aphids, because I do not want to use a product. But where are the ladybugs?

I think these tufa walls  have  drip watering  installed.

Oddly enough, in the  UK we  seem to have  lots  of  ladybugs already this  season. I fear  we  also have more than enough aphids to  feed them.

In the  May 2019 issue  of  International Rock Gardener - IRG e-magazine - the description of an Argentinian natural hybrid viola from the English/Chilean duo, John Watson and Anita Flores Watson – which they have named for a mutual Dutch friend, Kees Jan van Zwienen.

And there  is  much more  besides, of  course!!

with hybridizations, will they be able to make a rosulate garden viola, more easily cultivable? these rosulate, so beautiful, seem to me totally inaccessible..

Gerd: Could you explain to me how you make Viola cuttings? Viola walteri continues to blossom endlessly without making seed pods and I want to make several seedlings, if only to send you one. moreover its creeping stems do not make roots spontaneously. Is she able to make cleistogam flowers ?

Véronique,
Sorry for the delay - I was sooo busy in the garden (everything is growing and growing - especially the weeds).
For cuttings please look at the detached photos - I guess they are self-explanatory.  The last drawing by me shows a pot filled with a peat-sand mix (equal parts) - the cuttings are covered with a transparent plastic bag.
Keep the growing medium moist (not too wet). When the cuttings started to grow on you can cut some holes in the plastic bag in order to reduce the air humidity step by step. I guess stem cuttings is the easiest and most successful method.
According my books Viola walteri is able to build cleistogene seed.

my viola not hardy walked into the house with a lighting artificial
 and I have a flowering period of Viola verecunda (Sgrc 2018)
 it seems to have more fur and is all white except for the spur.
 I come home too Viola diffusa, concerned to see her described as an annual plant. it typically looks like your Viola diffusa, Gerd : round and hairy !
  also Viola clauseniana.. cuninghamii..
 I'm going to have to without doubt make them do everything the same a period of rest and more cold ?

Véronique,
Yes, your Viola diffusa looks very much like the species which often was named Viola papuana and turned out as a diffusa variant. At least the variant I cultivate is very tender and short living but not annual.
According your resting periode I guess you plan colder but not much below cero.
