How to grow

Cultivation This plant is listed on Schedule 9 of the UK Wildlife & Countryside Act as an invasive non-native species.

The RHS also encourages gardeners to find alternative plants to grow to those listed on Schedule 9. For suggested alternative plants see the Plantlife/RHS guide: Gardening without harmful invasive plants
