Rosinweed is a herbaceous perennial that typically reaches a height of three feet. Its leaves can be found in an alternate arrangement, occasionally appearing opposite, and are adorned with fine hairs. In late summer, it produces lemon-yellow flower heads that are roughly the size of silver dollars. The name "rosinweed" is derived from the resinous sap that, when dried, was utilized by Native Americans as a natural chewing gum for freshening breath. It's important to note that there is considerable local variation across its distribution.
