Nepenthes pitcher plants are on my mind as of the last week, and not just because I’m researching plans for a new greenhouse. (The Czarina offered last year to build a new Nepenthes greenhouse, and not just so she can demonstrate that the claw hammers in the house get used on something besides my head. She one with a bungee cord wrapped around it that she calls “Mjolnir”, and you’d swear that she can throw it around corners.) Last year’s drought still hasn’t ended, we’re not exactly looking as if we’re going to repeat 1990’s or 2007’s record rainfalls, and I’m in need of a new growing area that maximizes humidity without drying up a municipal reservoir to do so. I’m also looking for something that’s not too big and not too small, but juuuuuuust right.
All of the carnivores suffered last year from North Texas’s ridiculously low humidity, but the poor Nepenthes just looked ridiculous. As a rule, both lowland and highland Nepenthes can squeak by with average daily humidity going above 50 percent, with their producing larger and more elaborate pitchers the closer the relative humidity goes to “too thick to breathe, too thin to waterski on”. This is why I’m viciously jealous of Hawaiian Nepenthes growers, and it’s not helped by the Czarina hinting that we could always set up shop in Galveston. Dallas’s air may be a bit thicker than it was when another resident with lung issues moved here, but it’s not sopping wet enough to keep the Nepenthes outdoors, much to my regret.
And the history of the genus keeps getting more interesting. Longterm carnivorous plant enthusiasts may be familiar with the Nepenthes “Queen of Hearts” introduced by the wonderful folks at Borneo Exotics, but not know much more than the basics about it. Well, it turns out that “Queen of Hearts”, cultivated from seed saved from a cleared forest in the Philippines, is a new species now named Nepenthes robcantleyi.
As is the case with many Nepenthes species, N. robcantleyi may be extinct in the wild, or examples may still be available in hidden areas of Mindanao. Fellow carnivore enthusiast François Sockhom Mey is keeping closer tabs on developments than I could, so I refer you to him. From this hemisphere, though, it’s time to get that greenhouse built, because I will have one on display by the time the decade is over.
