Fantastic flowers!!

the altos on stone, you water them all how much,Paul ?

Viola rostrata is also interesting with its long spur, do you grow Gerd?

-- unfortunately not, seeds are very seldom avaiable.

Véronique, the pieces of tufa are small so I have to water regularly to keep it moist. In warm weather, this can mean every day.

 Germination of violet
I found that Viola pedatifida germinated very well from stored srgc seeds and I got 10 seedlings out of a limited number of seeds.
similarly for V. pumila and V. jooi

 Conversely, for example, V. sagittata, gives me only a small plant and V. vaginata, nothing at all for the moment.

I met this viola on a ski slope in the Vosges. the soil looked peaty.
 is it Viola palustris?

International Rock Gardener e-magazine (IRG#101) online tomorrow, includes the description of a new species of rosulate viola by John and Anita Watson....... just to let you know!

[Véronique Macrelle]

 a wonder this new Viola!

more modest Viola curtisii, the Curtis Viola encountered in the dunes of Stella  (Pas de Calais, France)

Veronique! Although writing from the land of rosulate Violas I wouldn't mind encountering a few Viola "modest" V.curtisii in my sandy soil garden here. Your picture is wonderful! Arturo

An unusual flower of spring flowering Viola canina alba

are there some species like V. pedatifida, V. jooi, V. orodrata, Viola mirabilis or other, that can also flower a little in autumn? with open flowers ..

is it accidental or are some conditions favorable to this autumn bloom?
 or do some species flower each year?

even in the springtime, they do not bloom systematically. it would be nice to understand why ...

These are a lot of questions and unfortunately I can't give a comprehensive answer
1. Viola odorata and its relatives (ambigua, hirta, suavis etc.) have a second periode with (open) flowers
    in autumn almost regularly -  although with fewer blossoms
2. I guess the autumnal flowering is induced by day length and temperature - perhaps also by first rain
    after prolonged drought in summer - this applies in particular Viola arborea which developes a
    full set of flowers regularly (in the wild and in cultivation)
3. Until now I can't imagine why it is so difficult here with some species - especially the East Asion ones
    (chaerophylloides, keiskei, mandshurica etc.) to achieve open flowers - even in spring -
    it is a small small comfort that they build a lot of seeds by means of cleistogamic flowers and some
    has nice coloured foliage

I hope very much that there some other growers of violets will step in here and share their experience!

Véronique,
Here is an example of a second flowering periode in autumn (Viola ambigua)
