Description

Taenidia montana, or Mountain Pimpernel, is a rare herbaceous flowering perennial in the carrot family native to Pennsylvania, West Virginia, Virginia, and Maryland and often found in shale barrens, open woodlands, and dense hardwood forests. It has a narrow range and is very habitat specific (that is, shale barrens) and, while its future appears to be stable, only a few plants are found at various sites; thus, in some of those states, it is listed as threatened or endangered. It is not commonly found in cultivation. The plant produces showy yellow blossoms in the summertime and is said to emit a rather unpleasant, anise-like, odor.

Mountain Pimpernel does best in peaty woodland soils that are shallow to deep and stony and/or loamy and in locations with surrounding shade or filtered sunlight in dry to medium water conditions. It will tolerate close to full shade, but prefers part shade and dry soil conditions. Established plants have good tolerance for drought.
