Rhododendron lapponicum

provided by wikipedia EN

Rhododendron lapponicum, the Lapland rosebay,[1] is a dwarf rhododendron species found in subarctic regions of North America, Europe and Asia, where it grows at altitudes ranging from sea level to 1,900 m (6,200 ft). It is an evergreen prostrate shrub growing to 20–45 cm (7.9–17.7 in) in height, with leaves that are oblong-elliptic or ovate-elliptic to oblong-obovate, 0.4–1.5 by 0.2–0.5 cm in size. The flowers are reddish or purple.

Despite numerous attempts, this dwarf species has proved difficult to cultivate, possibly because it requires very cool, moist conditions and snow cover for part of the year.[2]
