Morphological Characteristics

Sanguisorba officinalis is a herbaceous perennial with a rhizomatous root system. It has upright, branched stems that grow up to 1 meter tall. The leaves are alternate, lanceolate, and have toothed margins. The inflorescence is a dense panicle, bearing small, reddish-purple flowers. The fruit is a three-winged achene, and the seeds are dispersed by wind.

Diagnostic Identification Features
