Propagation
Sow seed in a greenhouse in early spring. If fresh seed is available, it is worth sowing some immediately, as viability may be short as with several other species in this family. Prick seedlings into individual pots as soon as they are large enough to handle and plant out in early summer. Consider providing some cold protection during the first winter.
