A low-growing native groundcover with heart-shaped leaves and maroon, tubular flowers hidden at ground level. Excellent for shaded woodland gardens and as a living mulch in permaculture systems.

Why grow it

Western wild ginger establishes quickly as a dense groundcover in deep shade where many other species struggle, making it a practical choice for woodland restoration and understory planting. Unlike some competing shade groundcovers, it tolerates dry summers well once established and requires minimal maintenance or supplemental watering in appropriate climates. Its low profile and spreading rhizomes make it useful for erosion control and as a living mulch layer, while its native range across the Pacific Northwest means it can support regional pollinator and insect communities when grown in its native habitat.

Watch out for

This species spreads steadily through rhizomes and may outcompete smaller herbaceous neighbors in confined planting areas, so plan spacing accordingly. Establishment can be slow in the first year, and plants may take two to three seasons to fill an intended area. Consistent moisture during the first growing season improves survival rates, particularly for transplants from nursery stock.
