Description & Care
Nepenthes singalana hails from the island of Sumatra, and is - I think - one of the most underrated species of tropical pitcher plant. Named after the volcanic Mount Singgalang, N. singalana grows throughout the Barisan range and is a true highlander - I wouldn’t suggest trying to grow this one in intermediate conditions long term.
That said, if you grow highlanders, I can’t recommend it highly enough! It has elegant, slender pitchers that vary in colour from green and speckled right through to maroon. The peristome is generally flared and starts bright red or orange, but darkens to a deep purple in good light. It’s also lined with prominent teeth - not as defined as the hooks of N. hamata or N. edwardsiana, but impressive nonetheless. The tips of the teeth - which are often a different colour to the rest of the peristome - point into the mouth of the pitcher, but most impressive are the long, forward-pointing teeth that line the tall neck right up to the lid. Zoom in on my photos above to see what I mean.
Other qualities I like about this plant include its propensity to flower - I have several females that put out inflorescences like clockwork - and the ease with which the cut vine and basals can be rooted. It’s also a very attractive plant even when young. Unlike many other species (N. veitchii along them), N. singalana produces dark, shapely, toothy pitchers when the plant is less than 10cm across. It grows at a moderate pace for a highlander, enjoys lots of bright light, and benefits from proper highland conditions.
