Cultivated Euphorbias

In the interest of better understanding what species might potentially "escaped" and become naturalized in the United States, it is probably worthwhile to at least try to list the exotic species that are cultivated here. The majority of the non-succulents are in the subgenus Esula and these form all the exotic species that are problematic. The other exotics are primarily succulent and are in the subgenus Euphorbia. I will not list all the plants that are too frost sensitive to be planted outdoors (at least, not at present; species with an "*" are too frost sensitive in most of the US) and will leave out almost all of the indoor succulents.

Euphorbia amygdaloides var. amygdaloides
