Very lovely Véronique, I hadn't realised that there were so many good foliage plants in the viola family. What is the scent like on these? I've got a pot of V. odorata 'Charmante Elvire' on my desk at the moment and am enjoying that delicate parma violet fragrance.
-
the fragrance of Viola odorata is present, but not very powerful outside, you make me want to try to put it on my desk a few hours to enjoy it better. the neighbors must laugh when they see me on all fours in my garden feeling a violet in the ground!
the other photographed viola do not really smell, but I will double check today.
Fortunately the Viola have pretty leaves, and often a foliage provided (covering) interesting, because some are difficult to bloom.
even Viola Sororia, which is much more imposing, makes very beautiful leaves in summer, I think.
Viola selkirkii is a miniature: flat foliage of maximum 4 cm in height. I think it is an excellent companion plant in the pots of others, without ever choking her neighbors.
-
Véronique,
Nice Fotos - your plants are earlier than mines here.
Do you cultivate Viola heartthrob (sic!) outside? I lost a plant after its first winter.
Gerd
-
Very nice Viola Veronique !
-
Gerd, As Viola 'Heartthrob' is a purchase last September, I repotted and kept in the greenhouse, then out when the foliage started.
what a good idea Gail put a pot of Viola odorata on his desk!it smells very good, more in the morning.
the latter bloom in the greenhouse:
here is Viola 'Silver Samourai' which gives off a sweet floral scent.
[attachimg=1]
the others do not feel:
Viola prionantha that makes smaller flowers this year (unlike Viola selkirkii)
[attachimg=3]
[attachimg=2]
-
Viola sororia, probably the priceana variety, always flowering.
[attachimg=1]
[attachimg=2]
and lastly the spring foliage of Viola mandchurica variegata in a (poorly) planting pot of Paeonia tenuifolia
-
That Viola 'Silver Samurai' is very pretty and as it is scented too it will definitely go on my search list...
-
From this website www.discoverthewild.co.uk (http://www.discoverthewild.co.uk) ..... images to help distinguish more common violas ....

Maggi,
Thanks for the hint!
Gerd

I took the opportunity of a short break of endless rain to rush into the garden and photographed
Viola adriatica - flowers a little bit damaged caused by permanent moisture.
Gerd
-
Viola adriatica is growing in the open ground ..
I have trouble acclimating my Viola in the garden, apart from Viola reichenbachiana and Viola odorata ...
so most are in pots, in the greenhouse in winter for the most part.
Gerd, among the seeds that you sent me in summer, some germinate this spring in pot, but outside the greenhouse: Viola epipsila, Viola rupestris, viola biflora, Viola striata ...
older seeds, I have a dense seedling of Viola aff colina and Viola ambigua
-
Véronique,
Congratulations - it seems you have excellent germination results!
I have also problems with some Viola species when planted in the open ground - even Viola ambigua in a sandbed seems to suffer. Otherwise Viola ambigua seeds around in the rock garden (good drainage).
Gerd
-
and do you know Viola papuana?
I find very little information on the internet about V papuana
I received seeds from the srcc, and I believe that one is germinating.
-
Véronique,
I received seeds of V. papuana frequently and it turned out as a Viola diffusa variant.
The latter one is a nice plant nevertheless but not hardy outside here.
I guess the 'real' V. papuana is shown on the link here.

I find very little information on the internet about V papuana
I received seeds from the srcc, and I believe that one is germinating.
Here is the page from its original publication ... https://biodiversitylibrary.org/page/11445270 - in Latin and German. Open the link to be able to enlarge the page properly - but I will post an image of it ...
[attachimg=1]
-
thank you Maggi.
I would have liked to know more about its culture, but I admit that the German completely baffles me
-
Véronique,
German does not help - there is nothing written about cultivation.
But - I still believe that your seeds are from another violet species - perhaps a V. diffusa relative.
Seeds of Viola'papuana' were distributet with an accompanying photo which shows the diffusa relative
by B & T World Seeds and sinced then the error was continued.
I'll post a pic of the wrong papuana and you will be able to compare your resulting species.
The real papuana would be great!
Gerd
-
This is the violet which I raised from seed wrongly labelled as Viola papuana -
plus two pics from a Viola species probably near to Viola alba from Montenegro
Gerd
-
merci Gerd
I will compare when they grow up, for the moment only I have 2 seedlings with 2 cotyledons..
you keep this viola strictly above 0 ° C?
the second violet is charming ..
Gerd, my Viola cornuta from the Pyrenees sprouted in autumn, but, they do not grow much, as if they remained dwarf: leaves of a few millimeters and very thin stems: I do not understand why ...
-
you keep this viola strictly above 0 ° C?
Yes, I try to keep them in the plus-area. Nevertheless it can`t be excluded that in some frosty nights
temperatures get down slightly below zero.
Sorry, no idea concerning your V. cornuta.

Viola odorata taking over my lawn (with my blessing!);
-
A viola lawn! How lovely- I have a dear friend who adores violas - I must tell her about this super idea.
-
Viola odorata taking over my lawn (with my blessing!);
So lovely! For me V.odorata is a bit shy flowering, it grows more leaves and less flowers. :(
-
Viola odorata taking over my lawn (with my blessing!);
A smart idea -it seems this species loves the competition from the grasses and mowing keep it compact -
I noticed this here in the neighborhood also!
Gerd
-
I just love it. some are also trying in my lawn, but I am far from this beautiful carpet ..
the blue - flowered odorata has much larger flowers than the white - flowered odorata. it also shows a tendency to look upwards[attachimg=1]
-
Viola 'Heartthrob' and Viola walteri ' Sylver Gem' become beautiful. Unfortunately, I can not reproduce in good color pictures of the viola 'Heartthob'.

Véronique,
Your violets are great!

Viola alba is just fine today - the second picture seems to show a hybrid (alba x ?)
Gerd
-
Viola odorata taking over my lawn (with my blessing!);
What a beautiful sight!
There is a place I like to hike in the spring just for a carpet of V. odorata, escaped from a garden of course (luckily it's a neighbourhood trail, not in a wilderness area).
-
Viola chaerophylloides "Beni Zuri" is quite vigorus, flowers profusely
with a strong pleasant fragrance and sows itself - an ideal plant for early spring
flowering.
-
Lovely photo of a very attractive plant Rudi. Just wish we could smell it...
-
it is very beautiful, Rudy.
I have a seed of this Beni (srgc) that sprouts ... hope
-
Nice photo and beautiful plant - and one of the Japanese violets which seems to flower regularly!
Gerd
-
Thanks for your friendly comment, the seedlings from last year are also in full flower.

I got this from a Minnesota NARGS chapter plant sale about 20 years ago. It was grown from seed from the NARGS Seed exchange as Viola sp. It seeds around a bit, but doesn't seem to be too invasive. First pic is in the shade lawn, it is about 10cm high. Second in a trough where it is 2.5cm, but can grow to be about the same size as the first pic. To me, it looks just like the Viola alba that Gerd posted earlier in this thread. But, I don't really know what to look for to differentiate species, and there could be similar species that I don't know.
Any help with an ID?

what a pretty Viola Rick!
maybe Gerd will know ...
-
I am for Viola alba - please look for the seed capsules which will occur later. If they are round, not explosive and not turning upwards it is Viola alba (without going into the subspecies range which is complicated).
Gerd
-
Thank you Gerd! This is exactly what I am hoping for: a set of characteristics that will help me identify. I will be watching this spring.
Any other tidbits anyone can add is appreciated.
-
These are
1. Viola reichenbachiana
2. Viola ambigua - which reappeared to my surprise in the sandbed
3. A pansy hybrid which is around here - parentage no longer comprehensible - I started with Viola hispida a long time ago but after that this species ' met ' other violets of the pannsy type for sure
Gerd
-
V. recheinbachiana is in full bloom at home in the garden: it is our local violet. it is also very floriferous.
the characteristics you describe for V. alba, do not they also apply to Viola odorata alba?
Viola 'Alice Witter' , (related with Viola sororia or Viola cucullata[attachimg=1][attachimg=2] ?)

Cute Viola Rick. I'm not a specialist but I found that also the stipules are many times important characters for Viola species ID.
If you can find a botanical description for V. alba then you may cross check one character; I would also press leaves/flower/stem, for just in case someone comes up later with other details.
-
Thanks, Gabriela. :)

Viola alba and Viola odorata have distinctive stipule, broad for Viola odorata, linear for Viola alba. Differences can be viewed here : https://www.florealpes.com/comparaison.php?compar_code_1=violaalbadenar&compar_code_2=violettesuave&nouveau=1 (https://www.florealpes.com/comparaison.php?compar_code_1=violaalbadenar&compar_code_2=violettesuave&nouveau=1) (alba on the left, odorata on the right).

Yvain's link does not open for me - but here are two to the two species :

Thanks Maggi, it worked till the navigator is opened... I modified the link so that the comparison tool show both species, it just now need to select the picture of the stipules of each species.
-
Thank you!

By coincidence , just seen this post on Twitter from Botanical Garden UPJŠ in Košice, Slovakia
"The white flowers of the Viola suavis just bloom. It is often confused with Viola alba, which is not growing in Košice and its surroundings. Viola suavis occurs with white or violet flowers in several places in Slovakia."

FloreAlpes is a great site, thanks to Franck Le Driant, and you can also compare Viola odorata with Viola suavis ;D

-
Yvain - very useful descriptive information! Thank you!
+ some pics made recently
1. Viola ambigua
2. Viola hirta
3. Viola spec. - perhaps a hybrid hirta/chelmea (difficult to differentiate when leaves are not developed)

I thought Viola growers might be interested in this Web Site. The Nursery in question and who have a National Collection of Violas, is situated in Dorset, just outside the small town of Bridport.
Our usual Wednesday trip out was to this Nursery the aim being to purchase a selection. Regretfully, and I should have been aware really, it was to late in the season either to view the Collection or to make purchases. I shall be going again in late Autumn.

I ordered 8 sweet/parma violets from them this spring; received good sized plants, quickly and very well packed.

Gerd,
Is rubella scented?
My wife said it is not. Sadly I cannot smell the scent of my favorite genus myself - so I have to trust her
(and I do) :)

Viola canina var. alba and Viola striata

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".
[attachimg=1]
[attachimg=2]
[attachimg=3]
-
Indeed - a superb form! I cultivate one with quite smaller flowers.
Gerd
-
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.

Viola sororia 'Albiflora'

Is this the tiniest Viola?

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.

I'm going to try

Viola hederacea from the Bay of Research
it's extra with its little carpet of leaves. I love it
.

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.
Gerd
