Growing Guide: Nepenthes stenophylla, fallax, and glandulifera

Nepenthes stenophylla

Recently, I participated in the North American Sarracenia Conservancy's early spring auction. In that auction, I won a Nepenthes glandulifera. It's a species which has only come into cultivation fairly recently. All three of these species are remarkably similar (so much so that there is controversy over whether Nepenthes stenophylla and Nepenthes fallax are actually the same species). All have long hairs which cover the pitcher body and long, cylindrical pitchers.

Nepenthes glandulifera

I've found Nepenthes stenophylla to be a very easy species in a highland tank, producing a pitcher on every leaf. It is somewhat slow growing compared to other highlanders, but a very good plant, if not especially colorful. I expect Nepenthes glandulifera to be similiar.

Here's a handy tip sheet based on my experiences:

Media: Airy highland mixes work well with Nepenthes stenophylla. Personally, I'm using a mix of 50% long fiber sphagnum and 50% perlite.
Moisture: I treat my Nepenthes stenophylla as a standard highland Nepenthes, allowing a small amount of water to be ever present in the tray in which the plant sits. This water level fluctuates. I usually refill the tray when it has drained completely.
Humidity: I am currently keeping my plant in a terrarium, and plan on continuing to do so, but I imagine that it would be possible to grow any of these plants on a windowsill.
Pot Size: I use whatever pots are available for my Nepenthes, so long as the root ball fits in the pot and there's a bit of room for it to grow. Generally, this means that the leaves extend slightly further than the edge of the pot.
Feeding: I use Maxsea Grow 16-16-16 Water Soluble Seaweed Plant Food Fertilizer applied foliarly on all my Nepenthes. I've also started filling the pitchers with a bit of Osmocote, and I believe that it more effective than a general foliar spray, though I haven't done comparative experimentation to confirm.
Temperature: Cool nighttime temperatures are a must for these species. A drop of 20 degrees Fahrenheit from day to night is preferable, with temperatures never rising above 80 degrees Fahrenheit.
Dormancy: There is no dormancy requirements for this Nepenthes.
Propagation: Either through seed or cuttings. Cuttings are remarkably easy for most Nepenthes, so that would be my preferred method of propagation, however, N. stenophylla is known for being a slow plant, so it may be difficult to make cuttings as it would take a while to grow large enough.
