In the garden

Symplocarpus foetidus is a wetland perennial from eastern Canada, recorded from New Brunswick, Nova Scotia, Ontario and Quebec, and is a member of the Araceae. It grows to roughly 0.5 m and is chiefly notable for the skunk-like smell given off when leaves are damaged. Plant it where the soil remains moist or wet: this species tolerates sandy, loamy and clay substrates provided they do not dry out. It is listed for full sun and will also appear in naturalised or shaded wet corners in gardens; hardiness H7 indicates it is fully hardy in UK climates (roughly USDA zones 4–8). Position with enough space for its leaves and for seasonal waterlogging. Use Symplocarpus foetidus in wetland gardens, along pond margins or in naturalised planting schemes where moisture is retained. Handle with care: bruised foliage produces a strong odour and the plant is toxic if eaten. Expect flowers in February to March, when the plant is usually visible rising from wet ground.
