Drosera arcturi

Alpine sundew

A small alpine sundew of bogs, tarns and seepages in New Zealand, Tasmania and the Australian Alps, with strap-like leaves 1-5 cm long that unroll like the pages of a book. After flowering it retreats into a horn-shaped winter bud (hibernaculum) that often lies under snow for months. It is difficult in cultivation and needs cool summers and a genuinely cold winter.

Where it grows wild

It grows in Sphagnum bogs, at the margins of tarns and burn pools, in seepages and along slow streams draining bogs, mostly at montane to alpine elevations in open, sunny, permanently wet ground.

It grows above about 1500 m in New Zealand's North Island but descends to sea level in the South Island and south-west Tasmania. The 9 GBIF records with elevation run 670-2087 m (median 1350 m), a small sample that misses the lowland southern sites.
