Selected cultivar of the delicate pimpernel, a perennial of the Primulaceae family, this horticultural form was found in the Studland nature reserve, in Dorset, England, on the wet moorlands of the British Atlantic coast. It shares with the type species its requirement for constantly moist, even waterlogged soil, in full light or light partial shade.
It forms a very dense creeping mat, with thread-like stems rooting at the nodes, covering the ground by only a few centimeters. The small, round, opposite leaves, of a bright and shiny green, are practically invisible under the mass of flowers in full bloom.
It is precisely by its flowers that this cultivar is distinctly different from the type species. They are noticeably larger, of a bright and vivid pink, with well-opened petals marked by fine darker veins and a fluffy white center. In its natural habitat, the flowering of the type species extends from May to August. In cultivation, 'Studland' blooms abundantly in spring, often as early as April.
It is suitable for wet rock gardens, pond edges, and bog gardens. It does not tolerate any drought and quickly disappears if moisture is lacking.
