Purple Pitcherplant
Sarracenia purpurea
γ΅γ©γ»γγ’
A carnivorous plant native to North America, cultivated mainly in greenhouses and biotopes in Japan. The leaves form tubular pitfall traps (pitcher traps) that capture insects with downward-pointing hairs and digestive fluids. Large reddish-purple flowers bloom in spring.
Identification Points
- βLeaves form tubular pitcher traps with a hood (wing) at the top
- βFlowers are large, reddish-purple with 5 petals and an umbrella-shaped receptacle
- βThe pitcher rim is recurved and secretes nectar to lure insects

Evolution Notes
Sarraceniaceae evolved independently as North American pitfall-trap carnivorous plants. The pitcher is a modified leaf, and the trapping mechanism functions through a combination of waxy surfaces, downward-pointing hairs, and the fluid pool.
