Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - best sown in a cold frame as soon as it is ripe in the autumn, it will then usually germinate in mid to late winter. Stored seed requires 8 - 10 weeks cold stratification at 1°c and should be sown as early in the year as possible[7]. Temperatures over 15 - 20°c induce a secondary dormancy in the seed[7]. 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 their first year. Plant them out in late spring or early summer of the following year.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Tolerates atmospheric pollution, excessive moisture and a range of soil types if they are moderately fertile[7]. Established plants are drought tolerant[7]. Plants are hardy to at least -15°c[7]. A fast growing tree[2].
