Burk's southern pitcherplant (Sarracenia rosea)

Description

Sarracenia rosea is a species of pitcher plant in the genus Sarracenia and is sometimes known as Burk's southern pitcherplant. It was previously classified as a variety of S. purpurea subsp. venosa (var. burkii). The proposition for the plant to be named a new species arose in 1999. This proposition was based on three main factors: S. rosea has larger flowers on shorter stalks; it produces light pink petals, a feature no other species in the genus exhibits; and it has a somewhat different pitcher structure than S. purpurea. A form which lacks anthocyanins has been described as Sarracenia rosea f. luteola.The species is native to the Gulf Coast of the Southeastern United States, and has been found from Mississippi to Georgia. However, the areas in which the plant occurs are being developed, so the species's habitat is threatened. However along with Sarracenia psittacina, this species readily colonizes drainage ditches along highways throughout the gulf states providing a somewhat more sustainable albeit less natural habitat. S. rosea is appreciably more shade-tolerant than the other members of the genus.
