The aptly named hummingbird bush reaches three to five feet and thrives in U.S. zones 7 through 10. Flowers bloom in red and orange. The bush's tube shaped flowers appeal to the hummingbird, in part because they access hidden nectar more easily than other birds. The hummingbird bush is drought tolerant.
One of the larger shrubs that attracts hummingbirds, the butterfly bush reaches six to 15 feet. It's fast-growing, drought tolerant and able to survive in zones 5 through 10. Different species of butterfly bush offer different colored blooms, ranging from blue to purple, red, pink and white. Dead flowers must be manually removed but blooms quickly regrow in season.
