About

Cassiope tetragona (common names include Arctic bell-heather, white Arctic mountain heather and Arctic white heather) is a 5 - 10 cm tall low growing plant native to the high Arctic and northern Norway, where it is found widely. It is a white flowered shrub in the Ericaceae family.

Where it grows

It grows on ridges, gravely slopes, heaths and tundra, often in abundance and forming a distinctive and unique plant community.

Uses

In the Canadian Arctic, indigenous peoples use the plant as fuel. Because of high resin content, it burns even when wet.
