Is this Viola jooi?

Grown from SRGC Seedex 2010,
sorry for the poor pic and the chewed flower!

It's possible - but without well developed leaves difficult to be shure.
Another possibility is one of the Japanese related violets of section Adnatae.
Sorry!

If it is V jooi, watch out for the second flush of flowers which are cleistogamous and set copious seed.  It's turned into quite a bad weed here.

This I grow as Viola jooi.

If that's a weed, I'll take it....

...... building seeds without having full developed (chasmogamous) flowers -
especially in situations where light level is low.

...cleistogamous...

It's a flower that doesn't open its bud, but self pollinates itself inside the bud so no flowers, just seeds.  And with the viola, they ping open to reveal the seed, so disperse around.  Gerd, why does it tend to happen more so on the second flowering? 

If that's a weed, I'll take it....  

Do you want some, Chris?  Are you at the DWE next weekend?
But don't say I didn't warn you    

[ChrisB]

I bought a plant in the spring Diane, its in a pot.  But if it grows well in the garden, I'd love to give it a home in my gravel bed.  See you soon.....

[Gerdk]

Gerd, why does it tend to happen more so on the second flowering? 

- I suppose it is a is a strategy to build seeds when conditions for pollination by insects get worse, for instance when plants became shaded by a canopy in forests.

But until now I have no idea why some viola species, especially Japanese ones of the Adnatae section refuse to show their chasmogamic (developed)flowers regardless of the light level given.

especially Japanese ones of the Adnatae section refuse to show their chasmogamic (developed)flowers regardless of the light level given.

I'm assuming V. chaerophylloides and V. mandshurica belong to that section? Neither have flowered for the 6+ years I've grown them...

(Also, V. keiskei: I have one with hairy leaves and pedicels that does flower, and another with glabrous leaves and pedicels that does not flower - are one of them misidentified?)

[ChrisB]

I grew one of these Japanese ones from seed once, and all it did was produce seed.  I thought I must be going mad at the time somehow missing the flower every time, so this thread has solved that puzzle for me.  Thanks.

[Pascal B]

Can someone explain to me what induces this behavior?. I collected one in Taiwan I know has flowered but in cultivation all it does is seed.....

I also can't get the darn thing ID'd so if anyone has any suggestions they are welcome.

[maggiepie]

I have both V. chaerophylloides and V. mandshurica in the garden and both are seeding around but they flowered in spring.
