Planting
Choose sun or partial shade and acidic, sandy loam with good drainage. It can grow in relatively poor soil and suits woodland edges or a naturalised border.
Care
For seed propagation, scarify the seed coat to improve germination. Expect some plants to be short-lived, and allow space for spread by seed and short rhizomes.
Before planting: Poisonous to people and pets if swallowed.
