The leaves are alternate, simple, with entire margins, up to 5 inches (12.5 cm) long and up to 2 inches (5 cm) wide. The bark is smooth and gray, with the inner bark mildly scented. The flowers are creamy white, up to 5.6 inches (14 cm) in diameter, with 6 to 15 petal-like tepals. The fruit is a fused aggregate of follicles, up to 2 inches (5 cm) long and pinkish-red when mature.

How to Grow and Care

Although different species of Magnolia can tolerate slightly different conditions. In general they will do best with slightly acidic, moist, loose, well-draining soil. To mimic Magnolia's natural conditions, amend heavy soil with peat moss and compost. Grow best in Zones 7-10, depending on variety, with a few cultivars hardy to zone 5. Full sun to partial shade. Moist, peaty soil can help Magnolias tolerate full sun. If you're pushing the limits of cold tolerance, avoid planting Magnolias in southern exposure since the leaves can be damaged by winter sun and flowers may open prematurely. Magnolias benefit from irrigation the first few years, then they are tolerant of moderate drought.

They need room to grow to their full mature size and width. While looking small when first planted, over time they'll grow to fill up the space.

Some varieties of Magnolia don't bloom until 15 years old, so be sure to choose one that's fits your needs and expectations. Grafted plants (rather than seed-grown) bloom sooner… – See more at: How to Grow and Care for Magnolias
