If you can figure out how to propagate it, I could send you cuttings. As I said before, I don't know anything about propagation of plants.
Michael Lindsey and Athens are both Calycanthus floridus but Venus is a Sinocalycanthus. I think that's why the flowers are so much bigger. I don't know if there are different ways of propagating them. But I think you'd like all three. They are relatively carefree.
