Nepenthes undulatifolia is a recently described species from just a few locations in Southeast Sulawesi. It's famous for its wavy leaves and peltate leaf insertion. Pitchers are nearly spherical and range in color from green to deep red. Overall, we've found this species to be an extremely vigorous grower for a highland plant. Some of our more mature vines can put on 3 feet per year. The plant for sale here is the exact one in the photos. It's a confirmed male clone and has great red coloration when established.
