I bought a few pots of Violet Wood Sorrel from Toadshade Wildflower Farm a few years ago. It is lovely but ephemeral. It does not like ho...Read Moret weather and goes dormant by the end of June here in the mid Atlantic region.

Although, Violet Wood Sorrel is native to a lot of the US (according to the USDA Plants Database) it is possible that the other comments refer to Broadleaf Wood Sorrel, Oxalis latifolia. Certainly the photos posted are of this species and not Oxalis violacea.

I got starts of this plant at an old homestead and planted it at the front of a shady border. It multiplied fairly rapidly but was not in...Read Morevasive. I love this one for its soft foliage, pretty flowers, and acceptance of poor soil in a shady location. My kids spent years harvesting tiny bouquets of flowers and it has always been their favorite.

The Cottontail Rabbit eats this plant occasionally, even though it is mildly toxic because of the presence of oxalic acid in the leaves.

In Illinois, this is the only Wood Sorrel with violet flowers that blooms in sunny areas. The flowers and leaves open up on sunny days, otherwise they fold up and "go to sleep." It is an attractive, but rather small plant. The leaves are supposed to be edible in small amounts.
