TREES & plants


Tulip-tree flowers are shaped like tulips.

The tulip-tree is one of the largest native trees in North America. It is a member of the magnolia family and has distinct tulip-shaped characteristic in its leaves, flowers, and fruit. The showy, goblet-shaped, orange-yellow-green flowers appear in late spring after the leaves; the cone-like seed clusters sit upright on the branches. The golden-yellow fall color of the tulip-tree makes this an excellent choice for large landscapes. 

This species is native to the Chicago region according to Swink and Wilhelm's Plants of the Chicago Region, with updates made according to current research.

Tree & Plant Care

Tulip-tree prefers moist, well-drained, slightly acidic soils. Tolerant of more alkaline soil.
As with all members of the Magnolia family, tulip-tree's fleshy root system prefers being transplanted in early spring, rather than autumn.
A consistent supply of moisture is necessary; tree will suffer from leaf yellowing when planted in a dry site.

Disease, pests, and problems

Aphids, scales, mildew, canker, and verticillium wilt are possible problems.
Fast growth rate causes the tree to be somewhat weak wooded.
Tulip-tree is tolerant of black walnut toxicity.
