Which Sarracenia species is known as the white pitcherplant? Sarracenia leucophylla is the white pitcherplant.

The species is named for the striking pale upper portions of its pitchers, which are patterned with reddish-purple veins. Its upright leaves form hollow traps topped by rounded, wavy-edged hoods. Although commonly called the white pitcherplant, it also has the names crimson pitcherplant and purple trumpet-leaf, which can cause confusion.

Sarracenia leucophylla is native to the southeastern United States, especially moist, nutrient-poor longleaf-pine savannas along the Gulf Coast. Its range includes Alabama, Florida, Georgia, Louisiana and Mississippi. The plant obtains nutrients by trapping and digesting insects rather than relying solely on poor wetland soils.

The species is sometimes confused with Sarracenia flava, the yellow pitcher plant. Colour is the useful clue: leucophylla typically has a white upper pitcher with strong red veining, while flava is generally yellow-green. Habitat loss, fire suppression and collection pressure have contributed to its vulnerable conservation status.
