Windowbox Woodsorrel

Description:

This is a perennial herb growing from a woody rhizome. There is generally no stem, the leaves arising on long petioles from ground level. Each leaf is made up of three leaflets which can vary in shape but are often heart-shaped. The inflorescence is a loose array of white to purple-pink flowers.

Habitat:

Native to Argentina, Brazil, and Uruguay, but it is widely cultivated as an ornamental plant and can sometimes be found growing in the wild as a garden escapee.

Notes:

Spotted along the trail at the Allatoona Pass Battlefield. It is a weedy plant, although it apparently is not invasive enough to be restricted in any state. (There are other Oxalis sp. listed on Invasive.Org)
