General Information
The shale barren rock cress is a biennial plant in the mustard family. This plant occurs only in West Virginia and Virginia and is found on mid-Appalachian shale barrens of the Ridge and Valley Province of the Appalachian Mountains. This plant is highly habitat restricted and the number of individuals per population is low, most with fewer then 20 individuals. Because this species is a biennial, it has two age classes containing nonreproductive and reproductive individuals. Young, nonreproductive individuals have leaves in a basal rosette. Potentially reproductive individuals are present in the form of erect, flowering plants lacking a basal rosette. The flowering stem is composed of 3 to 41 branches. The flowers are small with white or creamy petals. Seeds are yellowishbrown and contain a narrow wing. Mature plants reach a height of 16 to 40 inches.

» Life History
Habitat Requirements
Mid-Appalachian shale barrens are characterized by an open, scrubby growth of pine, oak, red cedar, and other woody species adapted to dry conditions and are found most frequently on eroding slopes undercut by a stream. Shale barrens are isolated islands of habitat with steep southern exposures with elevations of 1099 to 2494 feet, dry, relatively sparse vegetative cover,high temperatures, and low moisture in the summer.
Reproductive Strategy
This plant reproduces sexually and diminished reproductive output brought about by deer grazing may lead to extirpation of some populations. The shale barren rock cress may not be a strict biennial, meaning that the rosettes may persist longer than one year, thus delaying flowering and fruiting beyond the second year. Flowering occurs from mid-July until the first killing frost, usually around November, at which time the plant dies.
