Spectrum Magnolia: Vivid Pink Blooms on Broadly Oval Tree

Magnolia 'Spectrum'

This deciduous tree offers vivid pink flowers like 'Galaxy,' but with fewer, larger, and more deeply-hued blossoms. It grows up to 40 feet tall and forms a broadly oval outline.

Growing Conditions & Care

Grow in moist, well-drained, preferably acidic to neutral soil in sun or partial shade; magnolias do not tolerate wet feet. Flower buds are susceptible to late frosts; shelter large-leaved species from wind. Prune in late winter or late summer to prevent sap bleeding; prune minimally.

Propagation

Sow seeds in autumn or stratify. Root softwood cuttings in early summer. Can be layered in early spring, grafted in winter, or propagated by bud in summer.

Common Problems

Bacterial leaf spot, spot anthracnose, canker, dieback, butt rot, powdery mildew, anthracnose, fungal spots, weevils, snails, scale insects, thrips, planthoppers.
