Polypodium sibiricum

A small, very cold-hardy evergreen polypody of the boreal belt from Siberia and Japan across Alaska and Canada, where it forms mats on mossy rock outcrops and boulders. It wants a real winter freeze and cool, humid summers, so it suits an outdoor rock garden or shaded trough in a cold climate far better than a heated room.

Where it grows wild

Grows in thin moss and humus on cliffs, ledges and boulders, often acidic granite of the Canadian Shield and mountain rock in Hokkaido and central Honshu, usually under or beside open boreal or montane forest. Habitat detail here is generalised from the genus and the recorded range.

Recorded from sea level to about 1,280 m (median 700 m); at high latitude it grows near sea level, further south it is a mountain plant.
