Propagation

Seed - best sown as soon as it is ripe. It usually germinates freely. Stored seed is more difficult to germinate, it should be pre-soaked for 24 hours in warm water before sowing. The seedlings quickly send down a large taproot and so need to be in deep pots[

]. When they are large enough to handle, prick the seedlings out into deep, individual pots and grow them on until large enough to plant out.
Traditionally, the seeds are allowed to dry completely for a couple of months in a cool, dry place. They are then planted on top of a loose, moist soil mix, under a 5 - 8cm blanket of moist sphagnum in a place which is cool at night and warm in the day. This helps with oxygen exchange in and out of the seed coat, which breaks down natural growth inhibitors in the seed. Germination can begin within a few weeks[
