Propagation

Seed - is easy so long as they are pre-treated. Soak them for 12 - 24 hours in warm water, until they show signs of swelling. If they have not swollen by this time, carefully abrade the seed coat, being careful not to damage the seed within. The seed should now swell up within a few hours in water. Sow them in a nursery seedbed or individual containers in a semi-shaded position and germination should take place in 1 - 2 weeks. Young plants grow away vigorously and can be planted out when they are 20cm tall[
