Japanese Spurge

Pachysandra procumbens

The Story

Plant Bio

Pachysandra procumbens, Allegheny spurge, is a slowly spreading perennial groundcover native to the southeastern United States, six to twelve inches high. Bluish-green ovate leaves are mottled with silver and purple as they age, and short fragrant bottlebrush spikes of creamy-white flowers open at ground level in early spring, often before the new leaves.

This is the native alternative to Japanese pachysandra, which is invasive across the Northeast and forms sterile mats nothing else lives in. Allegheny spurge spreads slowly rather than running, its flowers are genuinely fragrant, and its foliage colours attractively with age instead of staying uniformly green. Slower to establish, and worth the wait.

Uses & Benefits:

Ornamental UsesSilver-and-purple mottled foliage and fragrant early spring flowers held at ground level.
Practical UsesA well-behaved native groundcover for deep shade that does not need containing.
Ecological BenefitsBees work the early flowers, and unlike its Japanese relative it does not displace native woodland flora.
