The Q&A Archives: Chocolate Cosmos from Seed

Question: I am wondering if I can grow chocolate cosmos (Cosmos atrosanguineus) from seed. I have never seen seeds for this plant in any catalog. I've saved some seeds and wonder if it is worth trying to start them myself next spring. Thanks.

Answer: Isn't their fragrance just heavenly? Chocolate cosmos are actually grown from a tuber, much like a dahlia. I doubt seriously you would get satisfactory results from the seed. In most areas (Zone 6 and below) these tubers must be removed from the ground during the winter months and stored until the spring (once again, much like a dahlia). You could always try the seed and see what "pops up". Let us know what happens!
