The Q&A Archives: Trillium Seeds

Question: I have recently planted three trillium plants and I am wondering if the flower will produce seeds. Can I harvest the seeds and plant them? If so, when is the best time?

Answer: Yes, you can collect and sow the seed, but germination is slow and it may take up to five years for it to grow and flower. Harvest seeds when ripe and plant immediately, or save them to plant in winter. They must be exposed to winter cold. If left undisturbed, the plants will gradually spread.
