About

Scutellaria cardiophylla, known as gulf skullcap and heartleaf skullcap, is a species of flowering plant in the mint family. It is native to Texas, Louisiana, Arkansas, and Oklahoma; it is considered a rare/imperiled species across most of its range. Skullcaps get their name from (and are recognized by) their crested calyx.

Its habitat may be rocky or sandy soil in seepage areas, ancient fields, banks, grassy regions in open woodlands, and woodland edges.
