The name means ‘dragon’s head’. If you have a vivid imagination, you might just make the connection on a clear day. The individual flowers are typical labiates, with a broad lip, and above that a hood, and can be quite showy in some species. The flowers are in whorls, with the leaves, and as they open in sequence up the stems they give colour for a good time.

Dracocephalum rupestre is a Dragon's head from China and north-east Asia that makes good clumps, with handsome purple-blue hooded flowers. over heart shaped grey-green foliage. Fragrant.
