Viola declinata

Viola species are not that easy to ID and when collecting seeds in the wild, usually in a hurry there is not enough time for proper observation/pictures.

For this reason Viola declinata, an endemic species from Carpathian Mts., it was offered as Viola cf. declinata in 2017.
Flowering now in the garden, it is a different story :) you can easily take hundreds of pictures and make measurements. The name is confirmed and those few who purchased seeds can label it as Viola declinata.
