How it is grown

Requires a light porous sandy soil in full sun. Plants are often found in very acid soils in the wild. This plant was inadvertantly introduced to the Hawain Islands in 1932 and has spread widely there. It is considered to be one of the most threatening of exotic species, invading native habitats and altering the fire and hydrology regimes.

Propagating it: Seed - surface sow in early spring in a greenhouse. When large enough to handle, prick the seedlings out into individual pots and grow them on for the first winter in a cold greenhouse. Plant out in late spring or early summer, after the last expected frosts. Division in spring.
