In the garden
Lysichiton americanum sits in the Araceae family and is native to the Pacific Northwest of North America. As a perennial herbaceous plant it is adapted to swamps, wet woods and stream margins; its most obvious characteristic is an unpleasant skunk-like fragrance. In the UK it is treated as a fully hardy (H7) bog species and will tolerate exposed winter conditions provided the planting spot is sheltered from drying winds. Select a shady or partially shaded position with consistently wet or moist soil: peaty, clay or loam substrates at acidic to neutral pH suit it best. Avoid free-draining, dry sites. The recommended exposure is sheltered, so position plants where they will not be baked by sun and wind; proximity to a pond edge, ditch or purpose-built bog bed is appropriate. Use Lysichiton americanum for bog gardens, wetland restoration or naturalising within permanently damp areas. Planting near paths or seating should be avoided because of the strong skunk-like scent and because all tissues are toxic if eaten (contain calcium oxalate crystals), so keep it away from places used by children or curious pets.
