Utricularia laxa

A small to medium terrestrial bladderwort (section Oligocista) from wet grasslands and the margins of pools in southern Brazil, Paraguay, Uruguay and northeastern Argentina. It is annual, so it grows and flowers in one season and must be kept going from seed. Grow it in constantly wet, low-nutrient peat and sand in strong light.
