, 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. Prey items such as flies, ant

. This re-ranking has been debated among carnivorous plant enthusiasts since then, but further morphological evidence has supported the split. The following species and infraspecific taxa are usually recognized:

  • Sarracenia purpurea subsp. purpurea
    • Sarracenia purpurea subsp. purpurea f. heterophylla
    • Sarracenia purpurea subsp. purpurea f. ruplicola
  • Sarracenia purpurea subsp. venosa

      • Sarracenia purpurea subsp. venosa var. burkii f. luteola
    • Sarracenia purpurea subsp. venosa var. montana
