Germination Information

Pre-treatment: Seeds were placed in clear plastic germination boxes on two layers of moistened blotter paper, and placed in a germination chamber with a 12 hr light/12 hr dark regime at 22§ C. The light regime was later altered to 15 hrs light/9 hrs dark and the tray was moved closer to the light source.

Establishment: Seeds began germinating within 2 days and continued to germinate over the next 2.5 months. The creamy white flowers bloom from June to September. Seed maturation is indeterminate over 2 to 3 months. Seeds are mature when the perianth is paper-dry and the hard, filled seeds dehisce readily. Seed is collected by clipping the inflorescences or hand stripping into containers. After collection, seed was dried and then placed in a standard freezer for 48 hours to remove insect pests prior to cleaning. Seed was stored in a brown glass jar at room temperature for 18 months prior to this study.
