Propagation
The hard coated seeds require scarification by placing them in hot water (90° C) for one minute or submerged in sulphuric acid 30 minutes. Alternatively mechanical scarification can be applied.
Sow the seeds in a well drained media and maintain a temperature between 20 to 30°C (68º-.86º F) Germination occurs within 10 days and when large enough to handle prick-out and pot up.
