This shrub is considered both a flowering shrub and an ornamental shrub. It is typically planted for both its visual interest and profusion of spring flowers. The star magnolia grows to a height of 15–20′ and a spread of 10–15′ at maturity. With showy, fragrant flowers, dark green leaves and striking gray bark, this hardy magnolia is a real standout. It thrives in nearly every location in the U.S. and works well as a single specimen or foundation plant.
