Viola 'Silver Samourai'. it is slightly scented. my big plant is preparing this year about fifty flowers!
this small cutting was made in September 2017

That's exquisite Véronique :)
-
Ohh!!! Véronique - that is wonderful!
-
Seems to be a good flowering species (hybrid?) of Japanese origin! Very nice!
Gerd
-
yes, it is a hybrid of which one of the parents is suspected to be V. coreana, although it is much more vigorous.
it produces only malformed cleistogamous pods.
it is associated or identical to Viola 'Dancing Geisha'.
the foliage is very beautiful too.
-
Véronique did you get your mother plant from vert tige nursery?
-
no, I had it a few years ago at a plant festival (Celles in Belgium) at Nursery Mandragora.

Viola selkirkii fo. variegata in the greenhouse. a miniature: 3 cm in bloom. the second photo shows the interressant foliage, later in season.
-
Yann, I got mine from Thierry Delabroye ; I grow Viola chaerophylloides too, reseeding like selkirkii in all the neighbouring pots :D
-
ah i didn't pay attention if he still has stock.. next visit :)

Just in flower
1.+ 2. a neat form of Viola alba - found near Krasno/Croatia
3. Viola jaubertiana

How to differentiate Viola alba from Viola odorata, Gerd?
I have some white viola mats in my garden ... not really fragrant.
I would like to be sure that it is Viola odorata
-

oh, V. chareophyllum ! so why did not I manage to get it from 2017 srgc seeds? can it still germinate this spring?
-
I have never tried to seed them as they do it themselves very well ;D, but I have often found difficult to get seedlings from Viola seeds.
"Germination Tips:
Sow immediately. The viability of these seeds is short or the species propagates best with fresh seed. Stored seed might be coaxed into germination with temperature cycling and patience."
If you get no germination, I could send fresh seeds to you in late spring, early summer ... ;)

with pleasure, Nicole ;)

Véronique - please have a look at the following link!
http://mikehackston.blogspot.de/2017/04/viola-odorata-in-introduction-to-family.html (http://mikehackston.blogspot.de/2017/04/viola-odorata-in-introduction-to-family.html)
Viola odorata has long stolones[/u], leaves orbicular-reniform, deeply cordate, widest at about the middle, the tip rounded.
Viola alba has shorter) stolons, leaves ovate to triangular ovate and also deeply cordate at base but the tip is slightly pointed.
Both species are fragrant and closely related and they interbreed.
Sorry - not easy (unfortunately the characteristics of the two species as noted in botanical literature are contradictoraly.
Gerd
-
Viola alba and odorata have also different stipules : broad and elliptic-lanceolate in V. odorata, linear and thin in V. alba. You can have both stipules on this site : http://www.florealpes.com/comparaison.php?compar_code_1=violaalbadenar&compar_code_2=violettesuave (http://www.florealpes.com/comparaison.php?compar_code_1=violaalbadenar&compar_code_2=violettesuave)
These caracteristics are useful to discriminate between these two species but be careful, there are some others. Suavis and hirta are the two other quite common in France but don't forget thomasiana, collina, pyrenaica which also have broad sepals !
-
I grew these Viola arborescens from SRGC Seedex seed which germinated in early December 2017.
I was thrilled to see the first flower buds but no flowers eventuated - straight to seedpod,
cheers
fermi
-
Cleistogamy (seedset without building open - chasmogamic-flowers) isn't unusual with a lot of violets - even with Viola arborescens.
You'll have a lot of seeds for multiplication ;D
Gerd
-
Thanks, Gerd.
I wondered if it was because we are going into Autumn and maybe they will actually form flowers in spring.
What do you think?
cheers
fermi
-
these Viola arborecens are already very large for a few months of culture, but I forgot that it is the beautiful season for you ..
most of my violets need to know a winter to induce the flowering of open flowers.
Viola banksii can flower anytime, but it never makes me cleistogamous flowers, or even seeds.
-
Hi Véronique,
V. banksii was known for a long time as V. hederacea in Australia due to confusion between the species.
I've found it can spread very, very vigorously by runners or stolons - it totally over-ran a rock garden I made a few gardens ago - but I think it still sets seed.
I now only have the all blue V.hederacea 'Monga Magic' (I'm not sure it if it's actually V. banksii) - which I'm about to plant out - hopefully it won't run riot ;D
cheers
fermi
-
I like it ! but I do not know if it is banksii or hederefolia
it is rustic to what temperature in your country?
here it resists in leaf until -7 ° C (greenhouse)
Outside I have not yet tested a plant installed enough.
I always keep a specimen as a houseplant in winter: here it is:
the second photo, where it is well bloomed, dates from the summer
-
I grow V. hederifolia too ; the flowers have more white on petals and seem higher than yours ; no runners but they sow themselves very freely in the garden and in neighbouring pots :D
-
I had seeds of V. hederifolia from the exchange srgc this winter. we will see if it grows.
V hederifolia is rustic in the garden ? and does it make cleistogames flowers ?
if it does not make any runner, it's easy to differentiate it from V. banksii, finally.
V. banksii is not self-fertilized, it never makes seeds alone.
-
Thanks, Gerd.

Fermi,
This species flowers regularly a second time in september/october in southern Spain - this may be induced by the beginning of the autumnal rains.
Here in cultivation I have open flowers in spring followed bei cleistogamous ones till autumn.
Germination is easy - i. e. it seeds around in the plunge material inside.
Gerd
-
V. Hederifolia was hardy in Zone 7, near Lyon ; I have never paid attention so I can't tell if it had cleistogames flowers or not ;)

Free flowering and very fragrant:
Viola chaerophylloides Beni Zuru

This could become the beginning of another obsession.
-
it's already an obsession for me! ;D
Viola chaerophylloides'Beni Zuru' is very beautiful Rudi. Is it completely acclimatised and reseeding alone?
-
Free flowering and very fragrant:
Viola chaerophylloides Beni Zuru
Congratulations - I had hardly never open flowers with all of these marvellous Japanese species.
Gerd
-
Just garden centre violas at my back door - but so pretty. I was given this pot as a Christmas Gift and in December the flowers were around the size of my thumbnail - now they are feeling very bold and the flowers are around 2-3 cms across! If they get any bigger they'll be pansies!
[attachimg=1]
-
Why do we try to cultivate all these rare and tricky species when such a lovely beauty exists?
Gerd
-
Dear friends, thank you for the kind replies. My plant had many seeds in the open garden with
and without flowers and I noted some seedlings in late autumn. Hope, that winter weather did
not kill them.
-
Gerd, how right you are!
-
These are
Viola (alba) dalmatica in the rockgarden
and
Viola ambigua in a sand bed
Gerd
-
Hi all ,
I have sown in 2016 seeds of Viola mirabilis ...
they are very well germinated ...
and now I have more that I need for myself :)
The plants starting now with flowering ! ( please look pictures )
I would offer it for swap ( maybe for other interesting Viola,Primula,Anemones )
Sorry only inside Europe
Best wishes
Hans

I'll gladly support you Maggi ! ;D ;D
-
Quite so, Luc, the flower-power delivered by these little cultivars is a great joy -and the more so since they are so "easy" !!
-
Are you still growing V. ambiga in the sand, Gerd?
the leaves of V. mirabilis are very beautiful, Hans, I have some germinations, and in miniature, they already look a little like it.
on the other hand, are the first leaves of Viola pedatifida whole, uncut? seeds have sprouted, but I have a doubt about the species.
Viola madchurica 'Fuji Down': I can not cultivate in the ground because of slugs or soil too clay, it sows only in pots
-
I'll gladly support you Maggi ! ;D ;D
One of my favourite types is "Jackanapes" with the contrasting upper and lower petals.
These are from last winter - "bloomer pots" from a nursery so not the "true" cultivar 'Jackanapes'
cheers
fermi
-
Are you still growing V. ambiga in the sand, Gerd?
Sorry, found your question just now (was away for one week) -
Yes, I grow Viola ambigua in a sunny position and in sand - and it does better than in ordinary garden soil.
I add some pics from the alpine house here
Gerd
-
waouh! V. pachyrhiza ! very nice !
is it so small that you grow it in 2 pot ?
-
Thank you Véronique!
Yes, V. pachyrhiza is quite small with very tiny flowers - the outer pot is filled with sand
(wet after watering) in order to keep the moisture longer in the small inner clay pot.
Difficult to explain in English - I hope this is halfway understandable.
Gerd
-
I understood.
and in the clay pot, what subtrate you give him?
-
Thank you Véronique!

You got it spot on Gerd ;D
-
David, thank you for confirmation!
I understood.

Véronique,
I use approximately 3 parts loam based soil and 1 part small (limestone) grit for smaller pots, for larger ones and woodland species
there is a standard potting mix and less grit in the mixture.
Gerd
-
For the first of May a bunch of violets
Viola striata - ivory coloured
Viola canadensis - bigger and white with prominent streaks
Viola rupestris rosea - the Teesdale violet
Viola reichenbachiana - blue
Viol sororia f. priceana - the Confederate violet/ white-blue
Gerd
-
what is Viola rupestris rosea ? the one on the right, in profile?
-
No, it is the only reddish coloured one!
Gerd
-
a walk in the dunes of Pas de Calais and a meeting with this very pretty violet, rare here:
Viola canina var canina dunensis (finally according to my determination, do not hesitate to contradict me if necessary)
-
Véronique, nice species - where did you find it?
This induces me to show two pics from my sand bed
1. Viola canina alba
2. Viola palmensis - which survived unexpectedly there despite of the harsh winter - although a little bit harmed
3. the same species - but inside
Gerd
-
and some more
1. Viola pumila - which did not well in a sand bed but much better now in well drained calcareous soil
2. Viola hederacea Recherche Bay- seeds once received from my late Australian friend Kim Blaxland
3. Viola anagae - from the Anaga Region/Tenerife
Gerd
-
I found the Viola canina dunensis in the middle of a big dune massif a little sported near Stella. the violet was rather in the sunny places.
I have some of your sheaths of Viola hederacea that germinate. Is this one?
-
this is the first time that Viola elatior flowers here. it is 30 cm high or more; but only one stem was floriferous.

Yes, the Viola hederacea shown is the mother plant of the seeds I have sent.

I found this photo from "Andy's Northern Ontario Wildflowers" on Facebook and thought it would be of interest here
[attachimg=1]
"Long-spurred Viola rostrata is distinctive because of its nectar spur on the flowers. This plant was growing in rich, moist soil of a deciduous forest, Meaford area, Ontario, close to Georgian Bay, May 13 2018."
-
Viola spathulata and Viola kosaninii growing in tufa and flowering now.
Paul
-
Wow, this can hardly be surpassed!
Congratulations!
Gerd
-
ooh little wonders! :o
-
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.
Gerd
-

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.
[attachimg=1]
-
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!
[attachimg=1]
-
a wonder this new Viola!
more modest Viola curtisii, the Curtis Viola encountered in the dunes of Stella (Pas de Calais, France)
[attachimg=1][attachimg=2]
-
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
Gerd
-
:P
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!
Gerd
-
Véronique,
Here is an example of a second flowering periode in autumn (Viola ambigua)
Gerd
-
nothing that does want to bloom in viola at home this fall, even at the odorata (I'm waiting to admire a new variety with pink flowers ..)
Viola prionantha bloomed for the first time this year for 4 years. the difference, I think compared to other years, is that it started growing much earlier in the season. a year when she had not bloomed, I thought she was dead because she reappeared very late.
-
Viola striata decided to flower again.
Gerd
-
:P
I hope that my Viola striata will germinate this spring ...
here is a species that I found 2 years ago, but not determined. I never got flowers.
do you have an idea of his species? this will help me to know his
need; it is easily sown, fortunately, but often collapses in the fall.
-
Véronique,
It looks very much like Viola eizanensis, or could also be Viola chaerophylloides - both very shy flowering here (obviously not in Japan according the pics in books). Both seem to be quite short-lived.
Gerd
-
my viola seems to have less cut leaves, but maybe it's because it's more shaded?
when I say that it is easy to sow, I mean that it is growing rapidly, this hotpot was sown in August.
however, only 2 that germinated on a large number of seeds.
the sowing of viola is really random. For the next seeds of violet that I will order at the srgc, I will try the GA3
here are my spring seedlings of Viola hederacea.
small because it was nibbled entirely by a beast this summer (there were only a few petioles)
I thought it could be confused with V. banksii, but it is different, very dwarf. it starts to stolonnize
-
the secret of violets: what happens in the cleistogamic flowers?
this is a very big magnification (not sure that this term of photographer is well translated here)
I snatched a sepal. the flower is already fertilized I think, because the ovary is already growing.
before, it seems that the pystil turns to the single stamen?
it's very minimalist! but it works almost every time ...
it is on the species that I think is Viola chaerophylloides, which has big flowers (compared to others). in V. sororia, cleistogamous flowers seem to remain underground.
[attachimg=1]
-
finally I finally have an autumn bloom: Viola odorata 'Orchid Pink'. a seedling from last year that sprouted in the spring.
the color is delicate, it gradually clears up
-
Some seedlings of Viola chaerphylloides ´Beni Zuri`are still in flower.
-
you grow it outside or in a greenhouse?
with what type of soil?
-
Veronique, I grow this viola in a lean and well drained woodland substrate in the open
garden now for the second season and hope, that it will stay so well with me.
-
it is probable that mine does not bloom because it is in pot! I have to acclimatize it in the garden.
I bought Viola Walteri online at " Promesse de fleurs"
this is the first time I see this species sold on this side of the Atlantic. Can anyone tell me more about this species?
-
Violate walteri - prostrate southern Violet from West Virginia, Maryland, Florida, Georgia and Texas.
Found in rich acid-soil forests in shade or half-shade.
It spreads by runners that root und form new plants. The leaves have a silvery appearance caused by very tiny white hairs. Cleistogenes are also present.
Not from my own experience but from Doretta Klaber (1976) Violets of the United States
Hardinesss is not particularly mentioned.
Gerd
-
here is Viola walteri 'Sylver Gem' that I received. She is still pretty despite the end of the season.
'Sylver Gem' would be a naturally more silvery form compared to the rest of the population.

Viola corsica has been flowering all summer with occasional dead heading by the rabbits. The first picture is from the middle of October and the second the middle of November with deer footprints all round :'

Very flowery for the fall!
Was October also warmer than usual at home?
in October, I still had some Viola dubyana, but not as much.
