Can anyone provide examples of specific cultivars that are either sterile (no seeds at all or seeds that do not geriminate) or hybrids that produce seeds that dont breed true to parents or revert to earlier crossed characteristics? autumn joy sedum and double scoop coneflowers come to mind, but i am sure there are more. i am hoping for a consolinated list (or ones you know that i can consolidate.) i am aware that Daves garden lists propogation methods if the cultivar is individually looked up, but i couldnt find a thread or list. Thanks!
