Water in Pitcher Plants: Which Species Need It, Which Don’t

A grower asked if they should add rainwater to newly arrived “Picture plants” (cobra, flava, etc.) or wait for new growth.

Jeff Dallas corrected the name: Pitcher Plants (think water pitcher). Only Sarracenia purpurea and Heliamphora hold water naturally—add distilled/rainwater to their pitchers. Trumpet types (S. flava, S. leucophylla) secrete enzymes only when prey falls in. Darlingtonia self-fills. He recommended the “Grow Carnivorous Plants” DVD series to avoid common myths.
