I have found this beautifull blue flower at a flower festival at Seoul. Anybody recognize what plant it is ? The plant about 12 inches wide and less in height. The flower about 2 inches wide

It looks like a Solanum of some kind but I don't know which one.

Thanks Sue. I try to google Solanum or Solanaceae Blue. And resulting some similar flower and anther arangements but the leaves are different.

I will try again. Thanks.

Looks to me like Exacum pumilum, but more blue.
Compare it to this one:
Exacum pumilum

Yes, you're right, it does Mike. Although Exacum pumilum only has four petals it seems. Here's another Exacum, this one is Exacum affine which has five:

Good call, Sue.
I never noticed the 4 vs. 5 petals.

Wow.. you are right. I have search Exacum, and one variety looks so similar to the plants in question...

Further searching, the variety maybe Exacum trinervium subspp macranthum. (With some cultivar name such as Kandy, Navy Star..)

I will mark it as solved. Thank you guys 😀
