Is this Viola jooi?

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!

Hi Gerd,
thanks, I'll post a pic of the foliage when it develops - I didn't realise it was deciduous and when it died down for the winter I thought I'd lost it!
cheers

Finally remembered to take a pic of the foliage!
Do these help clarify whether it is Viola jooi?

Fermi, Don't change the label - it is!

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.

There are many similar species,
Viola nagasawae Makino & Hayata is an accepted name,
do you think so ?

The phenomenon you noted is cleistogamy which specified the building of seeds without the appearence of open flowers before.
This is not uncommon in violets. It is suggested that this is a reaction to unfavorable circumstances as lack of light or lack of pollinators.
I guess there are other reasons which are unknown to me.
Personally I struggle with the same problem with Chinese/Japanese species.
