Native to tropical South America, but introduced to other areas as a garden plant. It is found in California, New Mexico, and Hawaii in the U.S.
A perennial plant due to the underground bulbs that persist each year, even if the foliage dies back due to heat, drought, or winter cold. Reproduction is from seeds and from the expanding bulbs. Plants prefer damp soils, and will be a weed problem in turf and landscape.
Plants are without stems, but send long stalks upward that terminate with the leaves. Clusters of many of these stalks occur on each plant. The leaves are divided into 3 heart-shaped leaflets that join at a common point at the tip of the stalk. The leaflets are broad and slightly hairy, and about 1 inch across. Flowers are produced in small groups on separate stalks that also arise from the bulb. These are bell shaped and dark pink to red to purplish in color.
Characteristicts Important to Control:
Physical removal will rely on completely removing the bulbs from the soil, and these may grow as deep as 8 inches. A systemic herbicide would be required to kill the bulb, and a selective broadleaf product will be effective when turf is infested.
