It is hairy silvery-woolly, bare later and usually has 2 leaves on small scales. The leaves are all basal, long-stalked, leathery, coarse and glossy dark green, the underside is lighter. The leaf blade is heart-kidney-shaped.
The flower heads have a diameter up to 15 mm. The bracts are in a single row, crowded and hairy brown-red woolly at the base. The flowers are purple.

The species grows on moist, humus-rich, mossy soil in coniferous forests, bushes and dwarf-shrub heath. In the U.K., it is known from a single location in Angus, Scotland.[2]: 811 It is uncertain whether the plant is native or introduced.[3]
