Sarracenia rosea is a newly named species that was formally known as S. purpurea subsp. venosa var. burkii and commonly known as Burke's Southern Pitcher Plant. The proposition for the plant to be named a new species arose in 1999. This proposition was based on three main factors. The first is that the plant has larger flowers on shorter stalks. Secondly, the plant has light pink petals, a feature no other species in the genus exhibits. Thirdly, the plant has a somewhat different pitcher structure than Sarracenia purpurea.^[1] A form which lacks anthocyanins has been described as Sarracenia rosea f. luteola.

The species is native to the southeastern United States Gulf Coast, 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.
