]. They tolerate 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.
