I guess varieties other than the grandiflora are invasive. This one seems to be a slow grower. Mine hasn't grown much in the last five years.
Other than the lemon vine /Pereskia aculeata none of the other varieties are sold here either.
I got most of what I have through the cacti and succulent groups we have locally. Here we exchange our plants with others in the group.
I don't do this any more as I have been cheated so often.
Thanks for the curation and support. I appreciate this very much.
Have a wonderful day @nikv
