Flower stems arise from axils of upper stem leaves, and not from the base of the plant. The lower 3 petals have purple veining. The species begins flowering on low, small plants and keeps on flowering for a long period, sometimes growing up to 2 feet tall. This is the only yellow-flowered violet in Missouri. Blooms March-May. Both the basal and stem leaves are heart-shaped with fine scalloping.
Viola pubescens (formerly V. pensylvanica)
Height: begins flowering low to the ground; often grows to 1 foot during its long blooming time.
Where To Find
Occurs in low woods, rich slopes, and wooded floodplains.
The showy flowers and attractiveness to butterflies make yellow violet a good native plant for rock gardens, fronts of borders, woodland gardens, and other situations. Please do not dig plants from the wild; instead, obtain them from an ethical nursery.
A number of bees, butterflies, skippers, and flies are attracted to the nectar of yellow violets, and fritillary butterflies use violets as the food plant for their caterpillars. Some birds, including juncos and certain gamebirds, eat the seeds.
About Wildflowers, Grasses and Other Nonwoody Plants in Missouri
A very simple way of thinking about the green world is to divide the vascular plants into two groups: woody and nonwoody (or herbaceous). But this is an artificial division; many plant families include some species that are woody and some that are not. The diversity of nonwoody vascular plants is staggering! Think of all the ferns, grasses, sedges, lilies, peas, sunflowers, nightshades, milkweeds, mustards, mints, and mallows — weeds and wildflowers — and many more!
