Ecology & Habitat

Description

Northern Golden-carpet is a small, creeping perennial, with braching stems up to 15 cm long that root at the nodes and are erect at the tips. The alternate leaves are chiefly clustered at the base or near the tip of the stems. Leaves are oval or kidney-shaped and 5-10 mm broad, with petioles up to 2 cm long and deep scalloping on the margins; the herbage is glabrous. The small flowers are borne in loose, few-flowered clusters at the ends of the stems; they lack petals, but have 4 green sepals that are approximately 1 mm long. The fruit is a two-lobed capsule that is partially embedded in the calyx cup.

Diagnostic Characteristics

The stoloniferous habit and small, apetalous flowers set this species apart from other Saxifrages in its habitat.

Habitat

This species occurs in mossy seeps, bogs, fens, and on marshy ground, muddy stream banks and shorelines, at elevations ranging from 0 to 3,300 meters (Freeman and Levsen, 2020).
