About
A vigorous, rootless, tiny-leaved, insectivorous plant, trapping minute prey in waterlogged soil by means of bladder-like traps. It is cultivated for its snapdragon-like yellow flowers which are borne on wiry flowerstalks from April through to August. Some of its leaves float on the surface of the water and some are submerged.
