Drought and salt tolerant grasses, from temperate regions in the northern hemisphere. Often found stabilising dune systems, or growing in stony open sites. We grow one species in our dry garden, as it introduces a strong vertical accent and a very glaucous foliage colour against a darker green background. Many of the other 40 species have foliage with hues of silver, blue and gray. With a rhizomatous habitat, some management is required.
