Nepenthes densiflora has a toothy peristome and maroon in color. It's one of my personal favorites. There seems to be other Nepenthes that are similar to this one. A few that come to mind are N. singalana and N. diatas. This species is a bit of a slow grower. It readily produces basal shoots and seems to prefer slightly shaded conditions. For my conditions outdoors, direct sun can heat the plant up and I think that's when it slows its growth. I grow them mainly in filtered light so that they don't get direct pounding sun all day long. They do vine and like hanging baskets as they get bigger. My smaller ones I grow on a deck in full sun but surrounded by other Nepenthes to offset some of the direct heat. This species is now available with some size to it. Borneo Exotics seems to be the main supplier of this species and plants available are much bigger than a few years ago. Because this plant is a bit of a slow grower, the bigger you can find the better. Once it gets to a vining stage the pitchers do get bigger. Recently Exotica Plants has produced some nice hybrids using N. densiflora. Overall this is a nice highland species to add to any Nepenthes collection.
