Best Carnivorous Plants for Hawaii: Tropicals Thrive, Temperates Struggle

On Oahu, grow tropicals: most Nepenthes (except ultra-highlanders), tropical Drosera, Mexican Pinguicula, and woolly sundews. Avoid Heliamphora, Cephalotus, Venus flytraps, hardy sundews, and Darlingtonia. Sarracenia may tolerate short dormancy in Hilo.

Water quality is critical. Nepenthes and Mexican Pinguicula tolerate harder water; sundews and Sarracenia need pure water. Rain catchment is ideal; otherwise use distilled or RO water.
