Tuliptree

Liriodendron tulipifera

Magnoliaceae · deciduous tree · native

You recognize Tuliptree by its unique cat-face-shaped leaves and bright yellow tulip-like flowers appearing in late spring. This fast-growing native reaches 80-120 feet with a tall, columnar form and smooth gray bark. The fall foliage turns yellow-green to golden, and winged seeds disperse by wind in autumn.

Tuliptree thrives in deep, moist, well-drained soils in full sun to partial shade. This vigorous tree establishes quickly but appreciates consistent moisture during establishment. Light shaping pruning controls form when young. Monitor for relatively few pest problems in PNW conditions. The rapid growth and graceful form make it valuable as a specimen or shade tree in appropriate landscapes.
