Cultivation details
Requires a well-drained light loamy soil and a sunny position[200]. Very resistant to salt-laden winds[11, 29]. This species is not very cold-hardy outdoors in Britain, tolerating temperatures down to about -5°c[200]. Plants succeed outdoors in milder areas of the country though they need greenhouse protection elsewhere[11, 29]. Very amenable to pruning, plants can be cut right back into old wood if required[200]. Closely related to P. crassifolium[11, 75]. The species in this genus are very likely to hybridize with other members of the genus[200]. When growing a species from seed it is important to ensure that the seed either comes from a known wild source, or from isolated specimens in cultivation. Plants in this genus are notably resistant to honey fungus[200].

Plant Propagation
Seed - sow when ripe in the autumn or in late winter in a warm greenhouse[78, 200]. The seed usually germinates freely. Prick out the seedlings into individual pots when they are large enough to handle, move the plants to a cold frame as soon as they are established and plant out late in the following spring[78]. Consider giving them some protection from the cold during their first winter outdoors. Cuttings of half-ripe wood, 5 - 7cm with a heel, July/August in a frame. Poor to fair percentage[78]. Basal ripewood cuttings late autumn in a cold frame[200].
