A delicate woodland perennial with small white flowers and characteristic hooked seed pods. Best suited for shaded garden settings in moist soil.

Why grow it

Circaea canadensis fills a specific niche in moist woodland gardens where many ornamentals struggle. Unlike taller shade perennials, it remains low and spreading, making it useful as a groundcover under trees or in riparian buffer zones. Its small white flowers appear mid to late summer when many woodland ephemerals have already faded, extending seasonal interest in shaded sites.

Watch out for

This plant self-seeds readily in favorable conditions and may spread beyond initial planting areas. The sticky seed pods readily attach to clothing and animal fur, requiring attentiveness if you wish to contain it. In very wet sites with standing water, roots may rot despite the plant's moisture preference.
