Purple Gerardia is an upright, slightly hairy annual. Its preferred habitat is woodland edges, roadsides, savannas and prairies. Distribution is throughout the Escambia region.

The leaves are opposite on the stem, consisting of one whole part, no stalk, linear to very narrowly lance-like.

The flowers are a raceme of heads that appear panicle-like. The calyx is lobed and has two lips; the upper lip is two-lobed and the lower lip is three-lobed. The color is lavender to purple (occasionally white). The throat is white-tinged with two yellow streaks and dotted with purple; four stamens. Flowers occur in late summer and early autumn.

Fruit is a capsule.

The related species, A. linifolia, is a smooth perennial with flowers that lack the interior lines. A fasciculata has leaves in clusters and A maritima is a succulent restricted to salt marshes.
