Nepenthes longifolia is another lowlander / intermediate that I've adapted to my outdoor conditions. The pitchers are usually greenish with some reds to them that are unusually long in shape. Probably that's where the name came from. I gave this plant a try mainly because I read that it grows up to 1100m in nature. Since N. longifolia wasn't terribly expensive, I bought it. It had a little difficulty adjusting at first. The plant never seemed to put out any new growth right away and pitchers dried up with the tendrils. But in the end, it has been worth the investment. The plant has adjusted and is doing fine. I haven't tried growing this plant indoors as a lowlander which I suspect would grow much faster and larger. If you plan on adapting N. longifolia as a highlander outdoors, be prepared for some plant stress. Mainly just pitcher drop off. The leaves stay normal and should produce new ones within the month or so. During winter, expect slow to no growth and some stress from reduced temperatures. N. longifolia would benefit if moved indoors during cold winter months. This species reacts similar in winter to N. albomarginata, N. campanulata, and other border line intermediates if grown outside yearround. For some reason I haven't seen this plant too readily available.
