Noteworthy Characteristics
Viola rotundifolia, commonly called round-leaved violet, is a stemless yellow violet that grows to only 5" tall. Basal, oval-rounded leaves and leafless flower stalks all rise directly from an elongated rhizome. Flowers are yellow with brown-veined lower petals. Flowers appear in early spring (March-April in St. Louis) as the leaves emerge. Native to rich woods from southern Canada and northeastern U.S. south in the Appalachian Mountains to Georgia.
Genus name comes from the Latin name for various sweet-scented flowers.
Specific epithet means round-leaved.
Problems
No serious insect or disease problems. Can be weedy. Foliage may decline in hot summer weather, particularly if soils are not kept moist.
Uses
Mass in shaded areas of woodland gardens, wildflower/native plant gardens or naturalized areas. Probably too weedy for rock gardens or borders.
