So glad I stumbled upon this post. I thought angelonia was an annual but at $5 a pot at the nursery I definitely am going to try to overwinter. I use my garage to overwinter plumeria, even though it can get cold in there on the coldest nights I think it will be okay. And I'm going to do pelargonium (geranium) as well. But everything looks so happy its hard to think about frost.... but last year we got frost on Halloween.
