Western Skunk Cabbage problems — and how to fix them
Western Skunk Cabbage (Lysichiton americanus) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Invasive in UK and Europe
Listed as an invasive non-native species under the Wildlife and Countryside Act in Great Britain. It is an offence to plant or cause it to grow in the wild in the UK. Always contain in a managed garden setting and never dispose of plant material into natural watercourses.
Slow to establish from young plants
Transplanted specimens may sulk for 1–2 years before producing full-sized leaves and flowers. Ensure permanently moist, rich conditions and be patient; once established it is long-lived and increasingly vigorous.
Slug damage to emerging spathes
Emerging flower spathes and young leaves in early spring are attractive to slugs and snails. Protect with wildlife-friendly slug controls; severe slug grazing on the spathe disfigures flowers permanently since they do not repair.
