Star Magnolia in Northeast TN garden

Multi-petalled Star Magnolia

Star magnolia (Magnolia stellata) is a multi-branched shrub or small tree which is native to Japan (USDA hardiness zones 4 to 8). This early flowering magnolia is noted for its compact form. A mature tree form grows 15 to 25 feet tall, 10 to 20 feet wide, and exhibits an umbrella-like canopy. Each flower typically contains 12-18 narrow thick fleshy petals (referred to as “tepals”).

In southern U.S. climes, its white flowers emerge weeks before the leaves, often a week or two before the official start of spring. In a colder northern spring it may wait to bloom in mid-April. White fragrant blooms are often damaged by spring frosts, but the remaining buds wait to open; flowering may continue over 2-3 weeks.

Star magnolia is easily grown in an average, medium, well-drained soil in full to part sun (4-hours minimum). It prospers a rich organic soil. It is best sited sheltered away from high winds; avoid a southerly exposure where flower buds may open too early and get frost-killed. Star magnolia suffers from few serious disease or pest problems when properly sited.

Star magnolia stands as a handsome small landscape tree or large shrub near a patio or in front of an evergreen background. Plant several together as a hedgerow. Star magnolia is best planted in late winter into spring, either balled and burlapped (b&b) or container-grown.
