- Description
-
Hairy yellow violet is a native wildflower from northeastern North America that naturally grows in rich deciduous forests, dry woods, meadows, low woods, sandy woodlands and other wooded areas. It is a member of the violet family (Violaceae). The species epithet is Latin and describes the hairiness of the leaf.
Hairy yellow violet grows well in part sun to part shade in loose soil with organic matter. This violet doesn't tolerate mowing. It tolerates acidic soils and self-seeds.
The alternate leaves of the hairy yellow violet are 2 to 4 inches long, with the upper surface a medium green with sparse short-pubescent. The lower leaf is light green and pubescent. The individual yellow blooms are produced from the axils of the leaves. The lowest petal will have brownish purple veins, which are a distinguishing trait for this species of violet. They often have a slight fragrance. Later on in the season, this variety of violet also produces small bud-like flowers that do not open but self-pollinate and produce seeds. This plant supports Fritillary (Boloria bellona) butterfly larvae. Nectar from the flowers attracts butterflies and bees. Members of the genus Viola support the following specialized miner bees: Andrena (Gonandrena) fragilis, Andrena (Gonandrena) integra and Andrena (Gonandrena) platyparia.
Use as a groundcover and in naturalized areas. It is a great companion plant for Trillium spp. in a native garden or woodland setting.
Insects, Diseases, and Other Plant Problems: Destructive insects may feed on the plant.
