Loebner magnolia

Magnolia  × loebneri

mag-NO-lee-ah ex LOBE-ner-eye
Magnolia x loebneri 'Leonard Messel'

This small tree is a cross of M. kobus and M. stellata . It has star-shaped flowers (3 to 5 inches across) with 10 to 14 narrow white petals, sometimes tinted in lilac-purple or pale pink. The blossoms are fragrant and appear before the leaves in mid-spring. Loebner magnolia grows to 30 feet tall.

CareGrow 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 in late winter or late summer to prevent bleeding of sap; prune minimally to maintain a healthy framework. 

PropagationSow 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.

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