1. Pour boiling water over seed, let stand in water for 24 hours, repeat process on seed that did not imbibe. It is called scarification.
2. Sow seed 6 mm (1/4") deep, tamp the soil, mulch the seed bed.
The seed germinates in 3 - 4 weeks at +25C (77F).
As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in a sunny position in the greenhouse for their first winter. Plant them out in late spring or early summer, after the last expected frosts, and consider giving them some protection from the cold for their first winter outdoors. Cuttings of half-ripe wood with a heel, July/August in individual pots in a frame.
Overwinter in a greenhouse for the first winter and plant out in their permanent positions in late spring or early summer.
