Oxalis violacea L.
Violet Woodsorrel, Violet Wood-sorrel
Oxalidaceae (Wood-Sorrel Family)
Synonym(s): Ionoxalis violacea, Oxalis violacea var. trichophora, Sassia violacea
USDA Symbol: oxvi
This is an erect, delicate plant up to 16 inches tall. The long-stemmed leaves grow from the base and at first are longer than the flowering stem. They are divided into 3 leaflets, gray-green to bluish-gray above and green to reddish-purple below, but similar in structure to those of O. dillenii. Like those of all wood sorrels the leaves fold downward, together, at night and in cloudy weather. There are 4-19 flowers at the end of each stem, lavender to pinkish-purple, the eye of the flower usually a deeper purple. The wide-spreading petal-like lobes are 1/2-3/4 inch long. There are 5 petals and 10 stamens.
This is a very common woodland and moist prairie species, which is cultivated occasionally in the North. It spreads rapidly by runners from its bulbs, and often flowers again in autumn after the leaves have died.
Oxalis is from the Greek word meaning sour.
