The Autumnalis cherry tree (Prunus subhirtella "Autumnalis") has a lot going for it. (For one thing, it's immune to the Asian ambrosia beetle -- a parasitic bug that's usually lethal to other cherry varieties.) The Autumnalis also has the added benefit of blooming during both the spring and fall. During moderate winter temperatures in the Southern United States, these cherry trees may bloom several times [source: Wilson Bros. Nursery]. Because of the late fall and early winter, the fragile, light pink flowers of Autumnalis provide an elegant contrast against the tree's leafless limbs. Even on the gloomiest days, Autumnalis flowers pop.
Be selective where you plant an Autumnalis, as these trees can get fairly large. They grow 25 to 35 feet (7.6 to 10.7 meters) tall, with a canopy spread of the same width [source: University of Florida]. Giving an Autumnalis enough room to grow will keep you from having to prune it -- yet another check in this tree's favor.
