The tuliptree 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 tuliptree makes this an excellent choice for large landscapes.
