I suggest sticking to the species names in the books for your plants if you want to use them medicinally. I’m unable to say for sure if the ones you mentioned will possess medicinal qualities. I did some searching, and couldn’t get confirmation. The species you mentioned are hybrids, meaning they’re crosses between two species in the genus. This crossing may mean the plant is more resilient, or has certain aesthetic qualities, but was likely not crossed for medicinal potency.
