Description:

Cuphea aspera is a perennial herb that produces flowering stems that are 8-16 inches tall. On these stems, small pinkish purple flowers appear from June - July. Leaves are rough and hairy, lance or oval shaped, with entire margins. The common name (waxweed) comes from the waxy or sticky feel of the upper stems, flower stalks, and flower tubes of the species, which are also covered with purple and white hairs. This species is found only in three counties in the Florida Panhandle. Of these populations, few are protected and many are threatened by encroaching development. (FNAI 2000; Clewell 1985)

This species has a very narrow range, restricted to the central Florida panhandle in Gulf and Franklin counties. 32 occurrences are believed extant, although some of these are in close proximity and might be considered the same population. This shade-intolerant species' open pine flatwoods and wet prairie habitat has largely been converted to slash pine silviculture; many extant occurrences are located in ruderal habitats such as roadsides. Threats include fire suppression, development, herbicide use, and incompatible mechanical disturbance such as mowing during flowering or disking/chopping.

Habitat is being destroyed by encroaching development. A shade intolerant plant, this plant has also lost much of its habitat due to fire suppression. (NatureServe 2001) Other threats include roadside mowing and herbicide applications.

No active management of this species known to be in progress.

Study the biology of the species and use that knowledge to implement necessary management plans. Currently FNAI (2000) recommends burning every 2 - 3 years. Avoid ditching, draining, bedding, or other disturbance to soil and hydrology. Determine true range and population locations.
