Eriophorum vaginatum
The Dark Peak is marked by heathlands, bogs, gritstone edges and acid grasslands containing relatively few species, with plants such as heather ("Calluna vulgaris"), crowberry ("Empetrum nigrum"), bilberry ("Vaccinium myrtillus") and hare's-tail cotton grass ("Eriophorum vaginatum") being dominant on the high moors. The dales of the White Peak are known for habitats such as calcareous grassland, ash woodlands and rock outcrops in all of which a much greater richness of lime-loving species occurs than elsewhere in the county. These include various orchids (such as early purple orchid ("Orchis mascula"), dark-red helleborine ("Epipactis atrorubens") and fly orchid ("Ophrys insectifera")), common rockrose ("Helianthemum nummularium"), spring cinquefoil ("Helianthemum nummularium") and grass of parnassus ("Parnassia palustris"). Specialised communities of plants occur on former lead workings, where typical metallophyte species include spring sandwort ("Minuartia verna"), alpine penny-cress ("Thlaspi caerulescens") (both known locally in Derbyshire as Leadwort), as well as mountain pansy ("Viola lutea") and moonwort ("Botrychium lunaria").
