- Description
-
Downy-Yellow Violet is a native wildflower with medium drought tolerance that naturally grows in rich deciduous forests, dry woods, meadows, low woods, sandy woodlands, and other wooded areas. Preference is for part sun to part shade in loose soils with organic matter. This violet doesn't tolerate mowing. It tolerates acidic soils and self-seeds. Use as a groundcover and in naturalized areas. It is a great companion plant for Trillium spp.
Differing from other Violet varieties, only 1 or 2 leafy stems are produced per root stalk. These 4-10" stems are light green, erect, and ascending or sprawling. The alternate leaves along these stems are 2-4" long, with the upper surface a medium green with sparse short-pubescent. The lower leaf is a light green and pubescent. The heart shaped leaves are unique to this variety.
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 variety of violet. They often have a slight fragrance. In the late 19th century, species in the violet family were used as a substitute for perfume and even chewed on as a breath mint. Later on in the season, this variety of violet also produces small bud-like flowers that do not open. They will self-pollinate. Both the flowers and the unopened buds will produce seeds.
Violets contain a chemical substance that may interfere with a person's scent receptors. After a period of time, the nose may become affected by the chemical substance, and the person can no longer detect the scent of a violet.
While beneficial insects such as bees benefit from the nectar and pollen produced by the blooms, several destructive insects feed on the foliage and other parts of the plant.
This plant supports Fritillary (Boloria bellona) butterfly larvae. Nectar from the flowers attract butterflies and bees. Members of the genus Viola support the following specialized miner bees: Andrena (Gonandrena) fragilis, Andrena (Gonandrena) integra, and Andrena (Gonandrena) platyparia. This plant is resistant to damage by deer. Butterflies and moths use this plant as a larval host. Birds and small mammals use the seed fruits as a food source.
Insects, Diseases, and Other Plant Problems: Destructive insects may feed on the plant.
