Dracocephalum rupestre is a plant species in the genus Dracocephalum, endemic to China.[2][3] The specific epithet, "rupestre", is derived from Latin, and pertains to the plant growing among rocks.[citation needed]
Dracocephalum rupestre is a rhizomatous herb having numerous purplish, upwards-rising and unbranching stems (15–42 cm) scantily covered in backward-pointing hairs. Triangular-ovate, sparsely villous leaves (1.4–5.5 × 1.2–4.5 cm) are numerous. Inflorescences are verticillastrate with bluish-purple petalled flowers.[4] Flowering period is from July–September.[4]
