dragonhead Interesting Notes
Dracocephalum ruyschiana, commonly known as dragonhead, is a clump-forming herbaceous perennial of the mint family which produces foliage to 8” tall spreading to 18” wide. It is native to montane grasslands from central Europe to Siberia. Square stems are clad with opposite, narrow, linear-lanceolate, matt green leaves (2-3” long) having entire margins. Two-lipped, strongly-fragrant, hooded blue flowers (to 1” long) bloom above the foliage to 12” tall on short axillary and terminal 2-6 flowered spikes from mid to late summer (July-August). Corolla of each flower has a two-lobed upper lip and a three lobed lower lip. Fruit is ornamentally insignificant. - Missouri Botanic Garden
