Illustration of Lapland Rosebay (Rhododendron lapponicum)

Lapland Rosebay is a tiny, mat-forming arctic-alpine shrub rarely exceeding 6 inches in height, growing in some of the harshest environments in North America — rocky arctic tundra, alpine fellfields, and windswept mountain summits. Despite its diminutive stature, it produces proportionally large, bright purple-pink flowers in early summer that stand out brilliantly against the barren landscape. The small, rust-dotted leaves are highly adapted to resist desiccation and cold. It has a circumpolar distribution and is one of the most northerly-occurring ericaceous shrubs.

Habitat
Arctic tundra, alpine fell-fields, rocky mountain summits, and windswept ridges from the high Arctic south to alpine zones of Quebec and Maine.
Diet
Flowers visited by early-season bumble bees and other cold-adapted pollinators; browsed occasionally by caribou and musk oxen.
