How to Grow Canadian Wild Ginger
Asarum canadense
Canadian wild ginger is a native woodland groundcover that thrives in moist, shaded spots. Heart-shaped leaves form a lush carpet from spring to autumn, then the plant goes fully dormant in winter. Small brownish-purple flowers appear in early spring, hidden beneath the foliage. Plant in shade under trees or along shaded borders, space 30 cm apart, mulch with leaf litter, and leave it alone — it spreads steadily without becoming invasive.
Yearly Lifecycle
Care Essentials
Rarely needed. Top-dress with leaf mould or compost in spring to mimic the woodland floor. No additional fertiliser required.
Watch For
- Slugs and snails on emerging spring growth
- Root rot in poorly drained or waterlogged soil
- Slow establishment in the first season
Pet Safety
Care Requirements
Light
Full to partial shade
Thrives in deep or dappled shade, ideally under deciduous trees. Tolerates partial shade. Avoid direct sun, which scorches the large leaves and dries the soil too quickly.
Watering
Consistently moist soil
Keep soil evenly moist, especially during the growing season. Does not tolerate drought — water during dry spells. Good moisture retention from leaf litter mulch reduces watering needs significantly.
Fertilizing
Leaf mould mulch annually
No synthetic fertiliser needed. Top-dress with leaf mould or compost in spring to replicate the woodland floor. This provides gentle slow-release nutrition and retains moisture.
Pruning
No pruning needed
Simply remove any dead or tatty leaves in early spring before new growth unfurls. The plant is herbaceous and dies back naturally each autumn without any intervention.
Spacing
25-35 cm apart
Space plants 30 cm apart for cover within 2-3 seasons. Wider spacing in dry or poor soil; closer spacing where soil is rich and moist and you want faster cover.
Support
No support needed
Low-growing groundcover with no need for staking or support of any kind. The rhizomatous spread keeps it stable on slopes and under trees.
