# Eastern Butterfly Weed

*Asclepias tuberosa subsp. tuberosa* L.

The Atlantic coastal plain plant, and the one Linnaeus named. It runs inland up the river valleys east of the Mississippi and is especially common in Tennessee.

## How to tell it apart

Leaf bases taper into the stalk or are bluntly rounded rather than squared or heart-shaped, and the leaf tips are blunter. Plants are 45 to 80 cm.

## Where it grows

Mainly a coastal plain plant east of the Appalachians. Records well inland, in Arkansas and Illinois for instance, may be garden escapes rather than native populations. It is uncommon in Rhode Island and of conservation concern there.
