Signature plant
Whorled Caraway is a summer flowering plant with distinctive whorl of leaves around the base of the stem which is an indicator of marshy grassland that is a Biosphere High Focus Habitat known as purple moor grass and rush pasture. It occurs on poorly drained, mainly acidic sites in lowland areas with high rainfall and wet soils and is often found with other habitats, such as wet heath, scrub and dry grassland.
In the past, purple moor grass and rush pasture was cut for hay during dry summers, but this practice is now in decline. Today, only a few sites are managed as hay meadows, and most are kept as rough grazing for cattle and sheep.
Purple moor grass and rush pasture is bursting with wildlife with up to 50 different plant species present in just a few square metres of grassland. Usually dominated by large tussocks of purple moor-grass it is also home to whorled caraway and damp loving plants like meadowsweet, ragged-robin and water mint. Purple moor grass and rush pasture is particularly important for its populations of butterflies. Find out more in the Biosphere Natural Heritage Management Plan here.
