Cuphea aspera

[1] This perennial herb grows up to about 40 centimeters tall from a woody, branching rootstock.

The opposite or whorled flowers have lavender or pink petals and reddish sepals.

This plant is somewhat similar to the nonnative Colombian waxweed, which has alternately arranged flowers.

[1] There are about twenty populations, most of which are located on private property owned by timber companies.

[2] Besides fire suppression and conversion of the habitat, threats include herbicide use and mechanical disturbance such as mowing.
