The delicately fragrant flowers are pinkish, bell-shaped and in nodding pairs at the end of 4-6 in. stalks.A low, delicate, matted evergreen plant with trailing stems having short, upright branches, each terminated by 2 pinkish-white, nodding bell-shaped flowers. Stems hairy. Twinflower was a favourite of the great Swedish botanist, Carl von Linne, who invented the system of binomial nomenclature.

A beautiful trailing plant of the North, this is the American variety of the European plant. It was named for Carolus Linnaeus (1707-1778), the father of modern botany, who was so fond of the flower he had his portrait painted with it. This charming plant makes a good ground cover in the woodland garden.
