Dracocephalum heterophyllum

Dracocephalum heterophyllum is a small perennial in the mint family, Lamiaceae. Its native range reaches from northeastern Afghanistan to southeastern Siberia and the Himalaya. Kew places it within the temperate climate zone. It is not native to Britain or Ireland. Plants For A Future gives its height as about 1 foot [0.3 metres]. This makes it a low plant for cultivated beds.

Its wild habitats include open slopes in dry country. It also grows on stony slopes beside mountain streams. Records describe ground with pebbles, clay, stone, and sometimes sand. These sites show the range of ground it occupies in nature. They do not mean it needs dry soil in gardens. The supplied species account gives no leaf, stem, or bark details. It also gives no flower colour, fruit description, or flowering season. Its flowers contain both male and female organs.

Garden guidance differs on the best place to grow it. Some reports favour sun and fertile soil with good drainage. Others favour a cool spot with a little shade. Plants For A Future recommends shelter and moist soil without waterlogging. It lists sand, loam, and clay as suitable soil types. The stated pH range runs from mildly acid to mildly alkaline. Good drainage remains important across these soil types. The source lists USDA hardiness zones 6–9. It also gives an older UK zone number, not an RHS H rating.

Seed, division, and basal cuttings offer ways to raise new plants. Sow seed outdoors in April or May. At 59°F [15°C], germination takes about one to four weeks. Small seed batches can start in pots within a cold frame. Grow young plants there through their first winter. Then plant them out in late spring. Divide established plants in spring or autumn. Take basal cuttings in April or May, retaining some underground stem. Keep these in light shade until roots form, then plant out in summer.

The root has a recorded food use when cooked. Plants For A Future gives it a low edible-use rating. It lists no known medicinal or other uses. The same source reports no known hazards and no weed potential. That hazard statement does not establish safety for people or pets. The supplied evidence gives no specific pest or disease information.
