Growth—

Succeeds in sun and in partial shade[2]. Prefers a moist, well-drained humus rich soil, preferably lime-free[3]. Prefers a mixture of sand, loam and peat[4]. In the wild the plant often inhabits exposed, moderately dry mineral soils, but occurs on a variety of soil types[2]. The life-span of a plant is estimated at 12 years[2]. Plant roots will usually survive a forest fire and then resprout[2].

Propagation

Seed - sow early spring in a cold frame[3]. Only just cover the seed and make sure that the compost does not dry out. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse or cold frame for their first winter. Plant out in late spring or early summer.
