Nepenthes × dyeriana is one of the most famous, spectacular, and historically significant tropical pitcher plant hybrids in cultivation. Originally created by breeder George Tivey during the late Victorian era (around 1900), it is highly prized for its massive, intensely colorful traps and robust growth habit. Because it descends from a single male cultivar, all authentic plants in the hobby are male clones propagated via cuttings or tissue culture.
