This is another of our Christmas flowers. Bougainvillea is a sub-tropical to tropical plant with which I have long had a love/hate relationship. The flowers are the little yellow-white spots and the red or magenta are actually leaves and not part of the flowers. It is a beautiful landscape plant but has huge and very sharp spines that will go through the sole of a shoe if you step on them the wrong way. Keeping these plants trimmed is not fun. There are dozens of varieties in Central America, but in the arid Southwest, we get about two or three. This variety is called Barbara Karst.
