We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus.
Succeeds in an open loamy soil[
], preferring a well-drained humus-rich soil in full sun[
]. Tolerates poor soils and atmospheric pollution[
Young leaves - cooked[
Seed - best sown as soon as it is ripe in the autumn in a cold frame[
]. It can be slow to germinate. Stored seed requires 6 months warm followed by 3 months cold stratification[
] and can be very slow to germinate[
]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in a cold frame or greenhouse for at least the first winter. Plant out in late spring or early summer.
