Cape Verbena is also known as Frog-fruit and Cape Weed.

Plant is a creeping perennial herb with 4-angled stems up to 3 feet long, bearing short, upright branches. Its preferred habitat is damp sandy soil, sloughs, pond margins, ditches, and low pine lands. Distribution is throughout the Escambia region.

The leaves are spatulate or oblanceolate, with an obtuse to rounded apex. The leaves are slightly toothed along the margin, usually on the upper portion of the leaf.

The flowers are small, white or lavender in color, and borne in dense heads that are held erect above the leaves. The flowers on the outside of the head bloom first, those toward the center later. Flowers occur in the summer.

A similar species that is known to the Escambia region is P. lanceolata. It can be distinguished by its leaves that are lance-like, tapering gradually toward the base and the apex.
