Janet, no i have not grown Ipomoea purpurea, but many species of Ipomoea grow wild here...it is everywhere. I have grown I. quamoclit and a large white night blooming Ipomoea (forgot the species) neither one was a big hit with the nectar lovers and so they have been replaced. If one of these volunteers should show up again, i will grow it at least until it can be identified. The problem when i do this is that i become fond of the plants and want to keep them. The solution is my neighbor who has a rancho on the edge of town that he has turned into an eco zone of sorts that attracts all kinds of bugs, birds, and critters. I give the plants that won't fit in my garden to him and he happily grows them at the rancho.
