Thank you very much for your comments and appreciation on that picture from Oxalis corniculata (very small flower). For the colors, according the flora from Gaston Bonnier, usualy the colors are yellow, and quite rarely, white. Interesting to understand that in Romania forest, oxalis is white ; could you try to share with us its photograph?
Hope to see you another time on treknature.
All the best.
Oxalis corniculata (14)
