• Bushes that grow in Texas have a USDA plant hardiness zone range from 6a to 9b. Plants within this range have an average annual minimum temperature range of minus 10 degrees to 20 degrees Fahrenheit. Grown in a wide variety of sizes and colors, many flowering shrubs that fall within this range grow 10 feet tall or higher, creating a commanding landscape presence. Their colorful blooms also enhance the landscape.
  
  

Buttonbush

• Buttonbush (Cephalanthus occidentalis) is a deciduous shrub with a rounded habit that grows up to 12 feet tall and 8 feet wide. It features tubular-shaped, fragrant flowers that appear in "dense, spherical, long-stalked flower heads in early to mid-summer," according to Missouri Botanical Garden. The projecting style of the buttonbush flower head give the appearance of a pincushion. The flower heads on buttonbush are favored by bees and, as they mature, turn into ball-like fruits that consist of multiple two-seeded nutlets. Buttonbush shrubs feature glossy, 6-inch-long, ovate to elliptic leaves that emerge in late spring and appear in pairs or whorls. Buttonbush grows best in full sun to part shade and humus-rich soil that is wet. Versatile, it tolerates a wide range of soil types. Grow buttonbush in USDA plant hardiness zones 5 to 9.
  
  

Sweet Pepperbush

• Sweet pepperbush (Clethra alnifolia) is an upright, flowering shrub that has a spreading growth habit and aggressive growth rate. It grows up to 10 feet tall and wide and features fragrant, late summer-blooming, white or pink flower spikes that resemble bottle brushes. The flowers on sweet pepperbush attract bumblebees and butterflies to the garden. Hardy, sweet pepperbush blooms are deer tolerant and the foliage turns a brilliant yellow in fall. Sweet pepperbush grows best in part shade and well-drained, moist soil that is acidic and fertile. Grow sweet pepperbush in USDA plant hardiness zones 3 to 9.
  
  

Winterberry

• Winterberry (Ilex verticillata), also called black alder, is a deciduous shrub with a slow to moderate growth rate. It grows up to 15 feet tall and 10 feet wide and has an oval to broad form with dense, fine twigs. Winterberry features small, creamy white flowers that are followed by the bright, red berry-like drupes that appear in tight clusters in fall and are favored by birds. The dark green, serrated to double serrated foliage on winterberry casts a purple tinge in fall to turn black with the first frost. Winterberry grows best in full sun to part shade and moist, organically-rich soils that are acidic. Versatile, it tolerates a wide range of conditions, including wet soil. Grow winterberry in USDA plant hardiness zones 3 to 9.
