Nepenthes neoguineensis is a species that I don't know much about. I bought my plant from the Nepenthes Nursery in Germany. He seems to be the only vendor that has this species available. My research has shown that this is a lowland to possible intermediate growing plant. I must confess that I've put this plant through hell. But he's survived! I originally tried him outdoors, but he didn't like that so I moved him indoors and grew him on a windowsill. It did much better but came down with some scale infestation. Now that the scale is gone, the plant is doing much better. I moved him back outdoors for spring and summer because there didn't appear enough air circulation for the moss to adequately grow and I didn't want to root rot the plant. It's adjusting fine to outdoor conditions but winter may be a problem. My plant has put out a small basal shoot and doing better than ever outdoors so I see no reason to move it indoors and stress it out. This is my only plant at this time. I do believe N. neoguineensis to be a hardy plant that should be grown similar to N. albomarginata, N. longifolia, and N. eustachya to name a few. The best photos of this species I've seen are at the Nepenthes Nursery.
