That wisteria story is wonderful!
I can’t say that I’ve had much luck with getting the Florida type plants to thrive here. I did have a plumeria plant that was successful for a few years, but I had to give it a LOT of attention. It grew too tall to bring back inside one year, so we could only manage to fit it into the unheated garage that winter. It didn’t survive. It was sad because I had devoted a lot of time to it.
What you may want to do with plumeria - is put Christmas-type lights on it with a timer to keep it warm over the winter months. This has worked for an area above me (as in higher elevation) that gets hard freezes (which kill plumeria)- and they’ve had success with this.
Sorry yours didn’t survive. I love hibiscus but cannot grow the “fancy” verities that are grown in the South and in Hawaii - I’ve lost every one that I’ve tried. They shouldn’t even be sold here and I’ve learned my lesson.
