How to grow

Cultivation Grow in deep fertile soil, avoiding hot, dry positions. Staking may be needed in exposed sites. It is more likely to be perennial if prevented from setting seed. Can be very variable in size.

Propagation Propagate by seed sown in a cold frame with good light, as soon as ripe. Move seedlings when young as older plants resent disturbance
