Utricularia ochroleuca

Pale bladderwort

A small, free-floating to loosely anchored aquatic bladderwort of acid bog pools across the cool Northern Hemisphere, with pale yellow flowers in July and August. It is treated as a hybrid of U. intermedia and U. minor and rarely sets seed, spreading instead by its stems. It needs soft, acidic, nutrient-poor water, sun, and a cold winter rest.

Where it grows wild

Shallow pools, hollows and ditches in raised bogs and other nutrient-poor to moderately nutrient-rich, acidic waters, in water about 20 cm to over 3 m deep. It usually lies against or is loosely anchored in the soft peaty bottom, with some shoots trailing into the mud.

Mostly lowland to low montane bogs in the temperate and subarctic zones; no specific elevation data was found.
