How to grow
The ideal position is a deep, moist, loamy soil in full or partial shade but it can tolerate drier conditions if mulched. A short-lived perennial.
Propagate by seed sown in a cold frame with good light, as soon as ripe.Exposure to light is required for germination. Move seedlings when young as older plants resent disturbance
