Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11
Botanical Name: Magnolia 'Spectrum' mag-NO-lee-ah Common Name: Magnolia Genus: Magnolia
This deciduous tree offers vivid pink flowers like M. 'Galaxy,' but with fewer, larger, and more deeply-hued blossoms. It grows up to 40 feet tall and forms a broadly oval outline.
Care: Grow in moist, well-drained, preferably acidic to neutral soil in sun or partial shade; magnolias do not tolerate wet feet. Magnolia flowerbuds are susceptible to late-season frosts; shelter large-leaved species from windy locations. Prune trees and deciduous shrubs in late winter or late summer to prevent bleeding of sap; prune minimally to maintain a healthy framework. 
Propagation: Sow seeds in autumn or stratify to hasten germination. Root softwood cuttings in early summer. Magnolias can be layered in early spring, grafted in winter, and propagated by bud in summer.
Problems: Bacterial leaf spot, spot anthracnose, canker, dieback, butt rot, powdery mildew, anthracnose, fungal spots, weevils, snails, scale insects, thrips, planthoppers.
