Answer: Cleome seed needs a cold treatment before germination, so put your seeds in moist compost, put in a plastic baggie, and place in the refrigerator for 2 weeks. Then plant in seed starting mix by sowing seeds on top of moist mix and pressing them in with your hand. They need light to germinate, so don't cover the seeds with additional mix. Cover the tray with clear plastic to help hold in moisture and place in a warm area, or provide bottom heat with heating cables or a seed starting heating pad. The seeds will germinate in 10-14 days at 70F - 75F degrees. As soon as most of them sprout, remove the plastic wrap and place them under a source of bright light for 14-16 hours each day. When the seedlings have developed two sets of leaves, transplant them into individual pots.
