Seed - sow in containers. Germination is usually 90-100% and takes 1-3 months at 21c. Germination is more rapid and successful if the seeds are first nicked or boiling water is poured on them, after which they are left to soak for 24 hours. Soaking in water overnight softens the seed coat and makes water absorption for germination easy. When the seed coat is nicked it may take only 6 days to germinate, though it is more likely to be 15 - 40 days. It is preferable to sow the seed directly into the soil. When seedlings emerge it is best to shade them for 8 days, then provide half shade for 4 - 7 days before exposing them to full sun. Seedlings need to be 3 - 4 months old, reaching a height of 40 - 50cm, before transplanting. The seed can be stored for at least 4 years at room temperature with no loss of viability <ref name="How to plant/cultivate"/>
