Overview

Viola hastata is a low woodland perennial growing 4-10 inches (10-25 cm) tall from a slender, scaly rhizome. Unlike stemless violets, it carries its leaves and flowers on an upright leafy stem, with two to four halberd-shaped leaves clustered near the top. The leaves are 1.5-3 inches (4-8 cm) long, triangular with a pair of basal lobes, and often marked with silver-gray mottling between dark green veins, sometimes flushed purple beneath. Flowers are 0.5-0.75 inch (12-19 mm) wide with five yellow petals, the lower three veined in brownish-purple, opening in early spring above the foliage. As in other violets, closed self-pollinating flowers form later near the ground and set most of the seed. The seed capsule splits into three parts that fling the seeds outward. It grows in rich, moist deciduous forest and goes dormant by midsummer in dry conditions. The plant spreads slowly and rarely forms large colonies, which limits its use as a groundcover.

Native Range

Viola hastata is native to the eastern United States, concentrated in the Appalachian Mountains and adjacent uplands from Pennsylvania and Ohio south to Georgia and Alabama. It grows in rich, shaded hardwood forests, often on slopes and along stream banks.

Suggested Uses

Planted in woodland and shade gardens, native plant collections, and along shaded paths. It combines with ferns, trilliums, and other spring woodland wildflowers. The early flowers supply nectar for small native bees.

How to Identify

Identify Viola hastata by its upright leafy stem topped with two to four halberd-shaped leaves, often mottled silver-gray, and yellow flowers held above them in spring. The arrowhead leaf shape with basal lobes separates it from the rounded or heart-shaped leaves of most yellow woodland violets. The similar V. tripartita has leaves divided into three segments rather than the lobed halberd form.

Bloom Information

Bloom Period

~3 weeks

Spring

Yellow flowers open in early to mid spring, generally April to May, lasting two to four weeks. After the spring display, the plant produces closed, self-pollinating flowers near the base that ripen most of the seed. There is no rebloom later in the season.

Care & Maintenance

Care Guide

Grow Viola hastata in part to full shade in humus-rich, consistently moist but well-drained soil. It needs the cool, leafy conditions of a woodland floor and declines in full sun or dry ground. A slightly acidic pH of 5.5 to 6.5 suits it. A layer of leaf-litter mulch keeps the roots cool and conserves moisture through summer. The plant may go dormant in midsummer drought and returns the following spring. It tolerates root disturbance poorly and is usually left undivided once established.

Pruning

No pruning is required. Spent foliage can be left to die back naturally, and a fresh leaf-litter layer each autumn supports the colony. Removing tree seedlings and vigorous neighbors keeps the planting open.
