Micranthes virginiensis
Virginia saxifrage
Overview
Micranthes virginiensis is a low perennial in the saxifrage family, forming a basal rosette of spoon-shaped to oval leaves 1-3 inches (2.5-7.5 cm) long with toothed margins. In early spring it sends up a leafless, hairy flowering stalk 4-12 inches (10-30 cm) tall that branches into an open cluster of small white flowers. Each bloom is about 0.25 inch (6 mm) across with five white petals and ten orange-tipped stamens. As the season warms the flower stalk elongates and the rosette persists at ground level. The plant grows from a short rhizome and roots into thin soil over rock. Native to eastern North America, it occupies moist ledges, cliff seeps, rocky woodland slopes, and stream banks, often where little else takes hold. It tolerates shallow, rocky soils but needs spring moisture and cool conditions. Foliage may go semi-dormant in summer heat. Plants spread slowly into small colonies and self-sow into rock crevices.
Native Range
Native to eastern North America, from eastern Canada south to Georgia and west toward the Great Plains. It grows on moist rock ledges, cliff seeps, woodland slopes, and stream banks.Suggested Uses
Micranthes virginiensis is grown in shaded rock gardens, crevice gardens, and native woodland plantings, and naturalizes on stone walls and ledges. Its early flowers draw small bees and other spring pollinators.How to Identify

Care & Maintenance
Care Guide
Micranthes virginiensis grows in part shade to full shade in cool, moist, rocky or gravelly soils with sharp drainage. It needs steady spring moisture but tolerates summer dryness once the rosette hardens off. The plant suits shaded rock gardens, crevices, and woodland edges. It needs little feeding and declines in heavy, wet soils in winter. Division of established clumps in fall or early spring renews vigor.Pruning
No pruning is needed. Spent flower stalks can be removed after seed drops for a tidier look. Damaged or dead leaves can be cleared from the rosette in spring.Container Growing
