Asclepias exaltata L.
Common Name: POKE MILKWEED

Coefficient of Conservatism: 6
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Nt P-Forb

This is our only truly forest understory species, usually in dry or rocky forests and savannas with oaks and other trees such as hickory, pine, and aspen; banks and borders, even roadsides; much less often in rich beech-maple forests or swamps.

The leaf blades are glaucous beneath, rather thin in texture, broadly elliptic, and somewhat acuminate at both ends. They resemble the leaves of Phytolacca (pokeweed), and the species has been known as A. phytolaccoides Pursh.
