Its name comes from sharing the running rootstock typical of "Teucrium chamaedrys" (wall germander). It was performed by Frank Key and Germander Speedwell. It leads through a region of esparto grass, white asparagus, common asphodel and germander. The latter is only known from "T. chamaedrys" (wall germander). Wall germander can be grown in USDA Zones 5-10. His favourites were Germander Speedwell, Creeping Tormentil and Common Chickweed. Teucrium marum, commonly known as cat thyme or kitty crack, is a species of germander.
