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.
Title: Re: Viola 2019
Post by: Véronique Macrelle on March 12, 2019, 05:54:57 AM
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, 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)

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
Title: Re: Viola 2019
Post by: Véronique Macrelle on March 18, 2019, 05:40:28 AM
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
Title: Re: Viola 2019
Post by: Gerdk on March 18, 2019, 10:54:14 AM
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).

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.

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!

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 ...

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.

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?

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).

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

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.

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.

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.

 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.
