Okay, so the holiday season is going full tilt, with the expected diminishing of daylight hours in the Northern Hemisphere. All of the temperate carnivores, particularly flytraps and Sarracenia pitcher plants, should be in full dormancy by now, and stay there until at least the middle of March. Nepenthes and Cephalotus pitcher plants may not need a similar full dormancy, but they certainly won’t mind a relative rest, and giving them lowered daylight hours increases the odds of their blooming in spring if they’re mature enough. Orchids, gesneriads, aloes, euphorbias, citrus…all of these definitely appreciate a bit of rest during the winter months. The trick is knowing HOW much of a rest, and of what kind.
For most, the rest period is determined by photoperiod, the number of light hours a plant receives per day. (One could argue that thanks to axial tilt, winter light intensity is diminished alongside the number of hours, but we’ll leave that out of the conversation for now.) As far as carnivores and protocarnivores are concerned, even species generally considered to grow all year around could use a photoperiod rest through the winter, with either decreased light or cooler temperatures or both. Tropical carnivores such as Nepenthes pitcher plants and bladderworts use photoperiod as a cue to store up energy for blooming in spring, and the tuberous sundews of Australia use photoperiod to prepare for emergence in the monsoon season. Want really spectacular blooms in spring with tropical sundews and bladderworts? Give them a rest now by matching the photoperiod of plants under lights with the outside dawn/dusk cycle. If that’s not practical, at least cut plant light to nine to ten hours per day.
With both plants under lights and ones in a windowsill, make sure to protect your plant from excessive artificial light outside of that winter lighting schedule. Moonlight is generally too weak to affect plants, and they’re already adapted to it, but street lights, porch lights, living room lamps, kitchen lights, and even nearby nightlights can adversely affect some plants’ ability to bloom. Poinsettias are an extreme example: getting those brilliant red bracts in time for Christmas requires putting them into a closet or other lightproof space at night. One flashlight, one open closet door, one porch light turned on at the wrong time before the poinsettia is ready, and you’re going to have to wait for next year.
The worst part of this is that it seems counterintuitive, especially for those of us with SADS. Right at the time when we’re craving more and more energetic lights, photoperiod-dependent plants are asking for a cessation of hostilities. Yes, not being able to enjoy them in winter is aggravating, but come spring, when they’re exploding with blooms, you’ll be glad to have let them sleep in.

Well, never let it be said that the Triffid Ranch doesn’t jump onto a social media trend a half-decade after everyone else does. For those who have lovingly nuhdzed me for the last two years about setting up an Instagram account, go check out @txtriffidranch right now. For those who haven’t, head over there anyway.

Because it’s that season, it’s time to look back on the basics. Both for beginning carnivorous plant enthusiasts and those experienced growers wanting to expand their range, you can’t go wrong with the 20-year classic, The Savage Garden by Peter D’Amato. You can get more detail on carnivorous plant morphology, relationships, and ecology with the Redfern Natural History volumes, but as far as good growing tips and propagation methods, you can’t beat D’Amato’s tried and true techniques. While the original 1998 edition is still a valuable guide, the recent updated version is worth the money, especially if you to get an autographed copy.
Music
Some of you fellow Eighties brats may remember the British metal band Bad News, either for the two pseudodocumentaries on the BBC’s The Comic Strip Presents, its live tour, or its sole album. A few may have specific opinions about lead singer and guitarist Vim Fuego, guitarist Colin Grigson, bassist Den Dennis, and drummer Spider Webb Spider Webb (as played by Adrian Edmondson, Rik Mayall, Nigel Planer, and Peter Richardson), and a few might even notice significant similarities between the two pseudodocumentaries and a pseudodocumentary that came out a year later about a band named Spinal Tap. For everyone else, it’s time for you to become familiar with a criminally overlooked vestige of Twentieth Century heavy metal history, if only for a celebration of the thirtieth anniversary release of the greatest holiday metal song ever written, “Cashing In On Christmas.”
