I’m on vacation, and I think this will be the last, and admittedly very short, entry I can post for February. The next one will likely be on Monday, March 2. — Daniel.
This is a different plant than the one photographed in San Miguel de Allende by David Tarrant two years ago (see: Bougainvillea glabra (unknown selection), and I’m afraid I don’t know Bougainvillea well enough to make an educated guess as to what this species or (more likely) cultivar may be. Feel free to take a stab at identifying it, if you like, and I can perhaps follow up in the comments with more information early next week if its identification can be determined.
