Amentotaxus species are generally natives of warm temperate, subtropical and tropical forested areas in east Asia. Most are tolerant of some frost, but only if there has first been a hot summer to fully ripen the wood. They therefore usually only succeed outdoors in warm temperate to tropical areas[

]. Seed voided by birds after they have eaten the fruit tends to germinate well, so scarifying the seed prior to sowing might be useful. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in pots in a cold frame. The seedlings are very slow-growing and will probably require at least 2 years of pot cultivation before being large enough to plant out. Any planting out is best done in late spring or early summer, after the last expected frosts[
