Propagation Notes Culver's Root
Fall Sowing - This is the easiest method. Seedlings grow stronger and sturdier when they are provided with a simple cold frame covering.
Growth Rate - Growth Rate - Very slow - Culver's root was started in February 2015 at the same time as other seedlings. Although, I had hundreds of sprouts, they are considerably smaller than I would have expected. Over the years, I have learned to wait until night and daytime temperature are closer to 70° F before planting.
Collect seed - Late in the fall, when it is brown and easily released from the flower stalk. Lean dried stem into a paper bag without breaking it. Start at the top and work your way down, loosening the seed as you go. I wear gloves, as the seeds are coarse. Only harvest what you need, I suspect that squirrels, chipmunks and birds will appreciate your generosity.
