Dryas is a genus of three species of dwarf perennial herbaceous plants in the rose family Rosaceae, native to the arctic and alpine regions of Europe, Asia and North America. The genus is named after the Greek nymph Dryas.
They are closely related to Geum, Potentilla and Fragaria, but are distinct in having flowers with eight petals (rarely seven or up to ten), instead of the five petals found in most other genera in the Rosaceae.
The flowers are white with a yellow centre (Dryas integrifolia, Dryas octopetala) or all-yellow (Dryas drummondii), and held conspicuously above the small plants. This makes them very popular in rockeries and alpine gardens.
