Answer: Strelitzia, or Bird of Paradise seeds can take up to 180 days to germinate and have the following requirements:
Do not chip the seedcoat but remove the orange tuft and soak the seeds overnight in warm water. Sow the seeds in moist sand, pressing them into the sand until only a small part of the seed is visible. Place the pots or trays in a dark area and maintain a temperature of 75F. Check frequently and keep the sand moist. After 7 days inspect the containers once a week. As soon as any bulges, roots or shoots are seen, remove the germinated seed and pot up in a growing medium of half peat and half sand. After repotting provide light and fresh air (to avoid damping off). Germination can start within 7 days and continue for 6 months or more.
Some seeds will produce roots without shoots and some will begin with shoots and no visible roots. Provide the best growing environment possible for your strelitzia seeds and you should have good success.
Maybe the best way to advertise your seeds is through a seed exchange column in National Gardening Magazine.
