The Q&A Archives: Does Ipomopsis Self-Sow?

Question: Will ipomopsis self-sow in Michigan, or should I save the seeds to plant next year?

Answer: Ipomopsis will self-sow where it's native in the West and temperatures don't dip below -15F (-26C), so you might let a few seeds fall to see if they germinate. To harvest seed to sow next year, make sure the seed is completely dry, then store in an airtight container in a cool, dark area. If you start them indoors, use peat pots or soil blocks, as the seedlings won't tolerate any root disturbance. Ideal germination soil temperatures are 55-65F (12.5-18C), and seeds should germinate in 10-15 days. Enjoy!
