Best grown in organically rich, neutral to slightly acidic, medium moisture, well-drained soils in full sun to part shade. Appreciates a root-zone mulch to help retain soil moisture. Also appreciates a location protected from strong winds, but avoid warm southern exposures which may promote premature bud opening in spring. Fleshy root system is easily damaged during transplanting, so it is best to select a landscape location carefully and leave this magnolia undisturbed once planted. Prune as needed immediately after flowering. Usually requires little pruning other than removal of dead or damaged branches.

Noteworthy Characteristics

The genus Magnolia consists of about 100 species (plus numerous additional hybrids and cultivars) of deciduous or evergreen trees and shrubs. Most plants feature large simple leaves and showy, sometimes fragrant flowers (yellow, white, pink or purple) which bloom in early spring before or while the leaves are emerging or in late spring to summer when trees are fully leaved.

Genus name honors Pierre Magnol, French botanist (1638-1715).

'Judy Zuk' is an upright, yellow-flowered, deciduous magnolia honoring Judy Zuk, a former President of the Brooklyn Botanic Garden. Over the first 10 years, it typically grows to 28’ tall and 8’ wide. It features tulip-shaped, fragrant yellow flowers with plum-flushed bases that bloom in early spring as the new leaves emerge (March to early April in St. Louis). Flowers are usually sterile. Obovate, large green leaves have entire margins. ‘Judy Zuk’ is sometimes listed as a cultivar of M. x brooklynensis.


Potential disease problems include leaf spots, anthracnose, canker, dieback and powdery mildew. Potential insect problems include weevils, snails, scale, and thrips.

Late frosts may damage flowers.


Excellent specimen or accent for sunny areas in the landscape where spring flowers can be appreciated. Small shade tree.
