In Arizona, the temperatures vary depending on the region. The state falls in USDA hardiness zones 5 through 10, meaning a wide range of plants can live there. These flowering shrubs can thrive in the majority of the areas in Arizona.
The winter honeysuckle (Lonicera fragrantissima) is a fragrant shrub that grows 6 to 8 feet high, and 8 to 10 feet wide. Leaves are deciduous but almost evergreen in the southern U.S. White, 1/2-inch flowers are produced in winter. Plant a winter honeysuckle in partial shade or full sun in well-drained soil. Propagate via cuttings, seed or layering (only in USDA hardiness zones 5 through 9).
The Ashe magnolia, or big-leaf magnolia, (Magnolia macrophylla subsp. ashei) is a fragrant shrub that gets on average 20 feet high and 20 feet wide. Leaves are 1 to 2 feet long and deciduous with white flowers that are 10 to 12 inches wide. Blooms are fragrant. Plant an Ashe magnolia in sun or shade in moist, well-drained soil. Propagate via seed or cuttings in USDA hardiness zones of 6 through 9.
The camellia or japonicas (Camellia japonica) is from the tea family of plants. It is an evergreen shrub that slowly grows to 20 feet high. Flowers are usually red or pink with yellow centers, 5 inches wide. Leaves are green and shiny. Plant a camellia in acidic, moist soil in partial shade in the southern zones, and sun in the northern zones. Propagate via cuttings or layering in USDA hardiness zones 6 through 9 (central Arizona).
The pagoda flower (Clerodendrum paniculatum) is from the verbena family of plants. It is an evergreen perennial shrub that gets 3 to 5 feet high, and 2 to 3 feet wide. Leaves are 1 foot wide with funnel-shaped flowers on panicles. Plant a pagoda flower in moisture-retentive soil in full sun or partial shade. Propagate via seed or cuttings in USDA hardiness zones of 8 through 11 (mid-to-southern Arizona regions).
The French hydrangea or big-leaf hydrangea (Hydrangea macrophylla) is a deciduous shrub. It is typically 3 to 6 feet high with ball clusters of flowers. Colors depend on the pH of the soil. Dark blue or purple comes from acidic soil, pink flowers come from alkaline soil and the white or greenish colors come from neutral soil. Plant a French hydrangea in moist, well-drained soil in partial shade or sun. Propagate via cuttings in USDA hardiness zones of 6 to 10.
