Overview

Asperula tinctoria, common name dyer's woodruff, is a plant in the family Rubiaceae, a native of much of northern and central Europe from France to Russia and also of Western Siberia.

Dyer's Woodruff faces severe population decline primarily due to habitat loss and degradation of its specialized grassland and woodland edge environments. Agricultural intensification, urban development, and changes in traditional land management practices have eliminated much of its suitable habitat across its European range.
