Utricularia gibba
Also called Conespur Bladderpod, Cone Spur Bladderwort, Swollen Spurred Bladderwort, Floating Bladderwort
Utricularia gibba, commonly known as the humped bladderwort or floating bladderwort, is a small, mat-forming species of carnivorous aquatic bladderwort. It is found on all continents except Antarctica.
U. gibba has an exceptionally small genome for a plant, despite having a typical number of genes. The sequencing of its DNA revealed only 3% repetitive DNA material.
Utricularia gibba has the reputation of being one of the easier aquatic bladderworts to grow, often being described as a weed in cultivation. In his 1998 book The Savage Garden: Cultivating Carnivorous Plants, Peter D'Amato advised that successful cultivation could be achieved with U. gibba floating in a small cup or bowl, within waterlogged peat, or even among the water-filled trays of other plants. It can also easily be grown in aquaria.
Utricularia gibba has a vast geographic range and is native to the eastern United States, southeastern Canada, Central America, the Caribbean, the western Mediterranean, Southern Africa and southern India. It is considered an invasive species in Hawaiʻi, Australia, Japan, Brazil, New Zealand, Singapore, Serbia, Hungary and the United Kingdom.
