White Persian Oxalis
Oxalis rosea (applies to red, white or yellow flowers)
Oxalidaceae (Wood Sorrel) Family
Plant is an upright, smooth to hairy perennial with a rhizome from which new growth emerges; woody crown. Preferred habitat is moist woods, yards and shaded areas. Distribution is throughout the Escambia region.
The leaf stalk is 6-12 inches tall with three segments which are broadly obcordate (inversely heart-shaped, with a notch at leaf base); about 1.5 inches wide, bright green and sometimes downy.
Flowers are large; petals about 1-1/2 inches long; sepals are downy and over-topping the leaf; slightly rotate (like a wheel). Flowers and leaf close at night.
Flowers are bisexual and symmetrical in form; ten stamens. Flowering occurs in early spring and persists through the summer; however, plant is maturing its seeds in summer and is therefore seen as a spring bloomer.
Fruit is a capsule.
This plant, though often called Persian Oxalis is actually an introduction to North America from South America; which escaped from the domestic garden and is widely naturalized along the Coastal Plain. It was; however, originally identified in Asia.
