Description
Distribution
The parent species, Sarracenia purpurea, occurs from the Northwest Territories in Canada, all the way down to southern Georgia, and from the eastern Rockies in Canada out to the maritime provinces. This species was originally divided into two subspecies, S. purpurea purpurea, and S. purpurea venosa. However, more recently, the southern group has been split further, with the southernmost populations in Florida, Mississippi and Alabama now classified as S. rosea. There is a disjunction between S. purpurea and S. rosea, as there are very few populations of either species in Georgia.
Sarracenia rosea is restricted to burned savannas and ecotones between river and forest in most areas where it occurs. It also can occur along power lines that are regularly mowed.

References and notes
This species was originally considered to be Sarracenia purpurea var. venosa. Rob Naczi proposed that S. rosea be a separate species, based on a lighter flower color, a shorter flowering scape, and a thicker lip on the leaf.
