Umbrella Magnolia

Magnolia tripetala (mag-NO-lee-ah try-PET-ah-lah)

Family: Magnoliaceae Native Understory (15-40 ft)

The Umbrella Magnolia is a flowering, medium-sized, tree or large shrub typically reaching a mature height of 30 feet with a 30 foot spread, although some may grow to 45 feet high. While uncommon, this understory, native tree is found throughout North Carolina. It has 10 to 24 inch leaves in whorl-like clusters at the end of stems and resembles the spokes of an umbrella, hence the common name. The 10 inch flowers are bowl-shaped and creamy white and bloom in the spring. The plant is typically found in the rich, moist woods, ravines, slopes and sides of streams in the Appalachian Mountains. The Umbrella Magnolia does best in organically rich, moist soil, sited in partial shade, with consistent watering. It tolerates close to full shade, but will grow in full sun, particularly in northern climates, as long as soils are kept moist. However, it does not like extremely dry or extremely wet soils. It should be planted in areas protected from strong winds to prevent damage to the leaves. The flowers are fragrant with an odor that some people find unpleasant. The wood smells bad when broken and is soft, spongy and easily broken. Diseases, Insect Pests, and Other Plant Problems: No known diseases. Magnolia scales and yellow poplar weevils can be a problem.
