A popular ornamental tree, the flowering dogwood is native to the Eastern United States. Growing 15-25 ft. tall, this deciduous tree is an ideal size for smaller yards. Not only do its blooms provide wonderful color, but they also attract bees and butterflies. The trees produce red fruits that songbirds and other wildlife eat. When selecting dogwood trees to buy online, make sure they are suitable for growing in your hardiness zone. Also, make sure you have the right growing conditions for the tree. Dogwoods can grow in partial shade to full sun, and prefer well-drained soil rich in organic matter. Their flower colors are most often pink or white.
