Indiana Phenology

Fagus grandifolia

Species Category Name: Woody

The American beech is a lovely shade tree that produces edible beechnuts, which are enjoyed by a wide variety of wildlife. It is unique from most other trees in that its bark remains smooth throughout its life. The surface root system of Fagus grandifolia can develop suckers that grow into new trees; entire beech groves can grow from the roots of a single tree!

Why observe?

Liriodendron tulipifera is Indiana’s state tree.

The tulip poplar is planted for reforestation purposes because of its rapid growth and the commercial importance of its wood, and is often planted as an ornamental.

This species has some wildlife value. The fruits provide food for squirrels in the late fall and winter months, and the white-tailed deer often browse on the twigs.
