I found this plant last fall, in a pot at the greenhouse. At that time I noticed it had 3 tiny leaves which makes me think it was a chance seedling. It was very small so I am sure it started from seed. I have had volunteer seedling from O. Triangulais many times. It has grown very fast over the last 3 months from a tiny seedling to the plant in the photo below.

I have never seen this Oxalis before and it looks like a cross between O. triangularis subsp. papilionaceae 'Atropurpurea' and Oxalis brasiliensis (or purpurea). I have hundreds of those in pots.
