Floating Bladderwort

Utricularia gibba | Also known as: Humped Bladderwort, Utricularia exoleta | Rating: 0 votes | Print / Pdf

A carnivorous aquatic plant, utricularia gibba is a finely developed mat-forming species of bladderwort. Commonly known as the floating bladderwort, stems are slender and light green, with stolons creating a mesh just under the surface of slow-moving bodies of water, and feathery leaves creating a lush cloud beneath the surface. On each leaf are tiny bladders to trap and absorb insects. In summer, stems grow above the water and produce bright yellow flowers with two lips – the lower of which is humped at the flower throat, thus the alternative name, the humped bladderwort. To thrive, it requires slightly acidic water that is not cold, with full sun exposure.
