This is a common weed here in Central FL, but adds a nice beauty to my garden. It likes the shady with filtered sun areas and not invasive at all. Especially likes my flower pots and makes a nice filler around many plants. Flowers in early to mid Spring and then again in early summer through fall.

According to Wikipedia all parts of the plant are edible, but should not be eaten in large quantities at one time.

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 hot 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 invasive. 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. I've also grown it in full west exposure sun and it did fine, especially in the shade of taller perennials. It makes a pretty 'skirt' for leggy plants.

This one just "popped up" in my yard next to some Ipheions. Luckily, I love Oxalis so I'm glad to have it. It's certainly not invasive as this is the first I've seen of it in 12 years here in my yard.

Primarily small long-tongued and short-tongued bees visit the flowers for nectar or pollen. This includes Little Carpenter bees, Nomadine Cuckoo bees, Mason bees, Andrenine bees, Green Metallic bees, and other Halictine bees. The bee Andrena violae is an oligolege of this plant and violets that bloom during the spring. Less commonly, the flowers may be visited by small butterflies or skippers. Syrphid flies also visit the flowers, but they feed on the pollen and are non-pollinating. The seeds are eaten to a limited extent by several upland gamebirds and songbirds, including the Bobwhite, Mourning Dove, Horned Lark, Field Sparrow, Grasshopper Sparrow, Savannah Sparrow, and Slate-Colored Junco. The Cottontail Rabbit eats this plant occasionally, even though it is mildly toxic because of the ... read more
