Prefers a light well-drained sandy soil in full sun. This species is not very hardy in Britain, though it should succeed outdoors in the southern part of the country, especially if given a warm sheltered site. Seed is rarely ripened on plants growing in Britain.

Seed - sow autumn or early spring very shallowly in pots of sandy soil in a greenhouse. Germination can be very slow unless you peel off the outer skin and pre-soak the seed for 24 hours in warm water. The seed usually germinates in 1 - 2 months at 15°c. When large enough to handle, prick the seedlings out into individual pots and plant them out in early summer.

Found in creosote bush scrub from sea level to elevations of 2500 metres in California.
