Our own selection of this species has dark blue snapdragon flowers covering a low, thick mound of rosemary-like foliage in early summer. Compact in a container and very easy to grow, just treat it as you would a Dianthus. It has been reliably hardy in Landenberg through rain and drought for many winters. Needs good drainage.

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
