Liriodendron tulipifera (Tulip Poplar)

One of the tallest broadleaf trees in eastern forests - the largest specimens exceed 150 feet - tulip poplar's tulip-shaped spring blooms provide genuine nectar value for bees, even though the flowers themselves often go unnoticed high in the canopy of a mature tree.

Species Overview

Liriodendron tulipifera, commonly called the tulip tree or yellow poplar, is one of the tallest native hardwoods in North America, often reaching 100 to 150 feet in height despite belonging to the magnolia family rather than the true poplars. It features distinctive four-lobed leaves and large, cup-shaped, greenish-yellow flowers with orange bases in late spring.
