Landscape Use

Star Magnolia is a dense oval to rounded shrub or small tree usually of thick constitution from the close set leaves and stems. It grows 15-20 feet in height with a spread of 10-15 feet. Bark is smooth gray. The bark is quite handsome on mature trees. Leaves are alternate, obovate to narrow elliptic and 2-4" long. Foliage is dark green in summer and yellow to bronze in the fall. Pure white, fragrant flowers emerge in April. Flowers are generally 3-4" in diameter. Since they open early, they can be susceptible to frost damage. Star magnolias are relatively disease and pest free. They may excellent specimen plants. Quite popular in the trade and often used in foundation plantings.
