Asarum caudatum (Western Wild Ginger)
Asarum caudatum (Western Wild Ginger) is an evergreen rhizomatous perennial boasting shiny, heart-shaped, dark green leaves, 2-5 in. wide (5-12 cm), which exude a spicy ginger fragrance when crushed. In late spring to early summer, fascinating reddish brown, cup-shaped, three-lobed flowers, ending in long graceful tails, are produced beneath the foliage. Western Wild Ginger spreads by creeping rhizomes to create a beautiful carpet within a few years. While a strong spreader, it is not invasive. Deer resistant, its large leaves and low growth make it a magnificent groundcover to plant under shade-loving trees and shrubs. More drought tolerant than the other species, Asarum caudatum is also one of the few wild gingers that shows some slug resistance.
- Grows up to 6-8 in. tall (15-20 cm) and 12-18 in. wide (30-45 cm).
- A part shade to full shade lover, it is best grown in average, neutral to acidic, moist, well-drained soils. Adaptable enough to thrive in sites that are wet in winter and to soils ranging from sandy to clay.
- Western Wild Ginger makes a great ground cover for shady areas of woodland gardens and is perfect for underplanting shrubs , edging or containers.
- Virtually pest and disease free but keep an eye out for slugs and snails which could damage the attractive foliage.
- Native to western North America from British Columbia to California and as far east as western Montana.
