Propagation
Surface sow fresh seeds when ripe (early spring) in a well-drained media, and maintain a temperature of 19º to 24º C. (66º to 77º F). Germination takes from 1 to 3 months. Prick out and pot up when they are large enough to handle and plant out after all risk of frost has passed.
Divide offsets in early spring and place in a moist sandy media until roots appear.
Note:
Care should be taken when handling the plant as it may cause skin irritation or allergic reaction and the seeds are poisonous if ingested.
