Utricularia sandersonii, Sanderson's bladderwort, is a species of flowering plant in the bladderwort family. Originally described and published by the British botanist Daniel Oliver in 1865, it is a carnivorous evergreen perennial, endemic to northern KwaZulu-Natal and Transkei in South Africa.

Description
Up to 50 cm (20 in) tall and broad, it grows as a lithophyte on wet, often vertical rocky surfaces at altitudes from 210 m (689 ft) to 1,200 m (3,937 ft).[1] Carnivory occurs beneath the surface, whereby tiny bladders on underground stems capture the micro-organisms which inhabit saturated soil. The visible parts of the plant are not carnivorous. Above ground it bears quantities of white flowers with pale blue markings, long forward-curved spurs and double lobes which resemble rabbits' ears.[2]

Cultivation
Utricularia sandersonii thrives in conditions that are relatively easy to replicate at home, and so has become a popular houseplant which can tolerate temperatures down to 1 °C (34 °F), but not freezing. It must be kept moist at all times and requires moderate lighting for continuous flowering. It is not able to perform self-pollination, so a male and a female specimen is needed for sexual reproduction, but asexual reproduction by fragmentation is much faster and easier. It has gained the Royal Horticultural Society's Award of Garden Merit.[2][3]
