Blue Hibiscus | Ok, I know we sometimes get a little carried away with our plant descriptions but this thing is just awesome! An evergreen shrub in the tropics, we grow it as an annual. Finely divided foliage looks a bit like some of the scented geraniums. But it's the stunning, purple/blue blooms that blow us away. Put this one in full sun either in a container or in the ground and be prepared to amaze your friends and neighbors.
