Bougainvillea packs a powerful color punch. This one is in my parents' yard in Scottsdale. Some nurseries around Boise sell bougainvilleas as "patio plants" - meaning, you can't leave them out in the winter or they will die. I've been tempted, but I don't have that much indoor space for plants, and I already overwinter geraniums each year. I saw a tiny purple flower peeking out of the foundation plantings yesterday. I'll share the early spring blossom tomorrow.
