Sarracenia purpurea range |
Sarracenia purpurea, commonly known as the purple pitcher plant, northern pitcher plant, turtle socks, or side-saddle flower, is a carnivorous plant in the family Sarraceniaceae.
Its range includes the Eastern seaboard and Gulf Coast of the United States, the Great Lakes region, all of Canada (except Nunavut and Yukon), Washington state, and Alaska. That makes it the most common and broadly distributed pitcher plant, as well as the only member of the genus that inhabits cold temperate climates. The species is the floral emblem of the Canadian province of Newfoundland and Labrador. The species was introduced into bogs in parts of Ireland, where it has proliferated.
It is an introduced and naturalized species in northern California. It is found in habitats of the native carnivorous species Darlingtonia californica, in the Klamath Mountains and northern Sierra Nevada.
Like other species of Sarracenia, S. purpurea obtains most of its nutrients through prey capture. However, prey acquisition is said to be inefficient, with less than 1% of the visiting prey captured within the pitcher. Even so, anecdotal evidence by growers often shows that pitchers quickly fill up with prey during the warm summer months. Prey fall into the pitcher and drown in the rainwater that collects in the base of each leaf.
