Propagation

Pre-soak the seed for 24 hours in warm water, ensuring the seed has swollen before sowing.
Sowing outdoors in situ is probably the safest way to start this plant off. If doing this, and seed stocks are in short supply, sow the seed in early spring around 5 - 10mm deep and place a moderate sized clear glass or plastic jar over the seed to help protect it from predation. Remove the jar once the plant is growing well.
Alternatively, sow the soaked seed in early to mid spring in a greenhouse. Either sow the seed in individual pots or pot up the young seedlings as soon as possible in order to avoid root disturbance. Grow them on in the pots until planting out in their final positions. It is usually impossible to transplant this species without fatal damage to the root[
