Hi there. I've had this great, easy to grow plant forever, but I've never known the correct name for it. It seems very similar to the Oxalis (Wood Sorrel) that I have but the leaves are a purple color and more triangle-shaped than the Oxalis. The leaves are bigger too. The flowers, which are just like Oxalis are a light purple. It grows from the same bulb type things as the Oxalis too. I've tried and tried but I can't seem to find anywhere online that talks about a Purple-leaved Oxalis variety. Can you help me out?
