American skunk-cabbage Lysichiton americanus
|Best Time to See|
A non-native invasive plant.
This plant is very commonly grown in bog gardens and is widely available from garden centres and nurseries. Most plants in the wild probably arise from garden material being dumped, as colonies quickly outgrow their space. It is likely that some wild populations have become established from seed dispersed from nearby gardens.
What's the problem?
With its very large leaves and rapid rate of spread, it can out-compete native plants and cause extensive damage locally. Given the popularity of this plant in gardens and its continued introduction into the wild, it is likely to increase.
