Thanks for the fast response to my question.
When I received my seeds (the skinny leaf type) I knew the warnings. I was told that the plant will grow in water so I planned to grow mine in an old fish aquarium so the plants cannot escape into the wild - also I will be able to bring the aquarium indoors for the cold months and let the plants grow under lights.
(Even though I do not have Adeniums
I will continue to check this most excellent thread.)
