Believe it's Bauhinia galpinii (synonym Bauhinia punctata) if it's a vine-y shrub or shrubby vine. We call it Red African Orchid Bush in my area but other common names are Nasturtium Bauhinia or Pride of De Kaap.
Name: Robert B Bradenton, Florida (Zone 9b) Plumeria to trade!!!
These trees get smacked hard in the winters sometime... usually once every 7-8 years we get an arctic blast of 32 in the middle of a 72 degree winter week.
Oh yeah, they're called "Blue Northers" here - 82 to 52 in about 20 minutes. We had a 20 years of 10a winters, then 2 back to back winters with hard freezes. Some palms were toast and that's when I lost my in-ground Plumeria.
Bauhinia galpinii for sure for sure. My favorite plant in the world and I don't own one!
Something must be done about that!
Very tough once established. Heat, drought tolerant. Something of a scrambler, but fairly slow growing so never a nuisance. Brick-colored flowers. (I don't know anything else with blooms this color.) Zone 9-10.
