We prefer to keep the vines pruned back to 24 inches or less, encouraging more branching and basal growth. N. rafflesiana - This widespread species is from Borneo, parts of Malaysia and Sumatra. It appreciates warm conditions and often makes its best growth during summer. Typically, the lower pitchers are fat and bulbous. Rosettes with lower pitchers eventually form vines with slender upper pitchers.
Colors vary wildly.
Pitchers should run about 5 inches when mature. Ours are vigorously growing, well-established young plants. N. ventricosa - is another good species for terrariums that is tolerant of household temperatures. This is a compact grower, producing less vining growth. Native to the Philippines.
