American Barrenwort (Vancouveria hexandra): Delicate Groundcover for Shade

Overview

American barrenwort (Vancouveria hexandra) is a charming, semi-evergreen groundcover native to Pacific Northwest forests. Growing 6-8 inches tall, it forms a lacy carpet of leaves that emerge bright green and darken with age, creating a two-toned effect. In mid to late spring, distinctive white flowers dangle on wiry stems, resembling tiny inside-out umbrellas with protruding stamens.

Growing Conditions

Light to full shade in humus-rich, well-drained soil. Mimics forest floor conditions. Spreads slowly but steadily by rhizomes. Ideal for filling gaps between taller shade plants.

Care and Maintenance

Cut away winter-burned foliage in early spring. Divide in spring to propagate or control spread. Water during dry spells. Low maintenance once established.

Common Problems

Vine weevil larvae may attack roots. Otherwise generally pest-free.
