Utricularia warburgii

Utricularia warburgii is a species of terrestrial bladderwort found in China, where it grows in sunny wet meadows at an altitude of 900 m. It belongs to the section Nigrescentes and is closely related to U. caerulea.

In the spring Utricularia warburgii produces 5–20 cm. flower scapes bearing 2-6 violet-blue flowers, 8mm in size and bearing a yellow splotch at the throat.

The cultivation of this species is not difficult, and is similar to other commonly cultivated terrestrial Utricularia. Plants are best grown in a mixture of peat and sand that is kept constantly moist to wet and placed in bright light conditions.
