Pinguicula gigantea

Pinguicula gigantea grows in the Mexican state of Oaxaca at an altitude of 688 meters or 2260 feet.

Pinguicula gigantea, unlike most Pinguicula species, has sticky upper and undersides of the leaves. The leaves have trichomes on them, which secrete a mucilage that traps prey. P. gigantea's leaves are among the largest in its genus. The species epithet, gigantea, describes this characteristic.

The flowers of P. gigantea are usually zygomorphic. The varieties of P. gigantea differ solely on their flowers, such as the 'blue flower' P. gigantea or the 'white flower' forms. Other forms have also been described. A dark purple flower exists in cultivation as well.[2]

Pinguicula gigantea is a tropical Mexican species of Pinguicula. Its dormancy is not regulated by temperature or light. Like most tropical species, its dormancy is triggered by lack of moisture. Very little precipitation falls during the winter in Mexico where this Pinguicula species lives. In order to survive in these conditions it forms non-carnivorous leaves and can handle dry conditions. When the plant emerges from its dormant period in the Spring, it produces new carnivorous leaves and eventually flowers.

Pinguicula gigantea can be propagated by seed or by leaf cutting. The disadvantages to propagation by seed include slow growth and the use of a second flowering P. gigantea plant to obtain better seed set results. Propagating by leaf cuttings has the advantage of a shorter time to the adult plant.

Pinguicula gigantea is available in cultivation.
