Clerodendron ugandense Verbenaceae Kristin Yanker-Hansen, Danville, CA A recent introduction, this blue flowered shrub has arching stems to 10’ and a somewhat open, airy appearance. It prefers hot sunny locations with regular water. It doesn’t like frost, but will stump-sprout after being frozen to the ground. Its rich flower color makes it worth figuring out how to grow it well. As it’s name implies, it hails from Africa. Photo by Don Gerimonte
