Icepocalypse now, walls of flame, billowing smoke, who’s to blame?

Icepocalypse Now

The hype started up early last Tuesday. We were in for snow, ice, asteroid strikes, blazing angels, Wal-Mart gift cards…the local meteorologists were whooping it up about this was going to be a storm for the records. By Wednesday, we all knew that something was up when we hit near-record high temperatures that afternoon and everyone started pulling out swimsuits. That didn’t keep everyone from laughing at the National Weather Service. “Oh, they say that all the time. They always predict a worse storm than what we actually get. Just watch: we’ll get a little bit of rain, and that’s it.”

Oh, we of little faith. The snowmageddon started sliding in from the northwest on Thursday afternoon, and it just kept getting worse. And worse. I have an incredible ability to wake up about thirty seconds before a power outage, and so I woke up about five minutes before the alarm clock went off, wondering “Why am I conscious right now?” when everything went dead for the next five hours. When the exemplary crews at Garland Power & Light weren’t able to get power reestablished right away, that’s when we knew this was going to be bad.

And to stop the immediate comparisons to your local weather and how “this isn’t so bad,” that’s true. Kinda. This was definitely the worst ice storm I’ve seen in Texas in the 34 years since I first moved here, exceeding the big storms of 1983, 1996, and 2011. We almost never get ice storms, much less ones of this intensity, and this one compared favorably to ones I experienced in Michigan when I was a kid. In Michigan, everyone has snow tires, heavy-duty ice scrapers and snow brushes, and other regular accessories for a typical winter up there. We don’t have snowplows, salt trucks, and tire chains because they might be used once every ten years or so. Hence, we’re caught flatfooted nearly every time. And this one? Nobody was prepared for this mess, because we simply don’t see storms like this.

Fields of ice

On a personal level, the storm and the power outage tag-teamed me. First, specialized greenhouse tape specifically purchased so it wouldn’t go brittle in the cold went brittle in the cold, and the north wind blew out a panel on the main greenhouse. Combine that with the outage cutting heat at a critical time, and all of the thermal mass I put in last October didn’t make up for the sub-freezing drafts. I’ll have to wait until things warm up, but it looks like at least a two-thirds loss of everything inside, including a new line of bonsai Capsicum peppers intended to be premiered at the next show. It may be possible to salvage, but that has to wait until temperatures rise again and I can perform a decent evaluation.

On the bright side, at least the Czarina and I weren’t insane enough to be vendors at the scheduled Fair Park Holiday show in downtown Dallas. That one was shut down early, but probably more a matter of a lack of vendors than the worries about weather. But about that later.

I’m also not complaining more, because the damage here was a lot less than that right around the area. Most of North Texas’s trees are various oaks, which generally don’t shed their leaves until spring, which meant they made wonderful nucleation sites for the incoming ice. They’re also not adapted to dealing with large amounts of ice, either, so local trees’ branches aren’t adapted to shedding or carrying huge amounts of snow or ice weight. With more flexible trees, such as crape myrtles and mesquite, they obligingly flattened to the ground and waited it out. The same thing with small oaks, such as the three-meter-tall oak that obligingly impersonated Charlie Brown’s Christmas tree when saturated with ice. Larger trees, though, and saplings from more brittle species just snapped. Expect photos shortly of the mess preventing my neighbor from being able to open his garage door for the two tons of shattered oak blocking his driveway.

And the temperate carnivorous plants put out for winter dormancy? That’s going to have to wait until spring. The layers of ice definitely killed off any still-living traps and phyllodia that the plants could use for photosynthesis, but most are used to worse conditions than this. The Sarracenia purpurea, for instance, should be right at home. In the meantime, while the ice lasts, I get views like this:

And one little bit of good? I’ve spent the last four years attempting to get results with growing the South African proto-carnivorous plant Roridula in Texas. One of the hardest problems is getting the seeds to germinate, and I tried everything. Scarifying the seed coat to encourage germination. Putting the potting mix in a smoker and smoking it heavily before adding seeds. Chilling the seeds before planting them. No results, and looking over the wreckage in the greenhouse made me think about just pitching them and giving up. Wouldn’t you just know that this sort of chill was exactly what Roridula dentata needed to get up and going? Now just to keep the seedlings going, as apparently decent air circulation is essential, and I don’t dare risk bringing them inside if they’re this happy just to lose them to fungus infections. And so it goes.

The definition of insanity

Okay, so last year’s seed experimentation didn’t work quite as well as I’d thought. Of course, you try predicting a “drought of record” back last January. Looking at the list of floral experiments from 2011, and it’s only slightly less painful than Bhut Jolokia-based jock itch creme. (Interestingly, the Bhut Jolokia plants were some of the only successes in 2011, and they’re going to make spectacular bonsai this summer.) Triggerplants, Nepenthes, Sarracenia, Drosera…on and on and on.

One of the learning-experience projects involved trying to see if the South African protocarnivore Roridula will do well in Texas. For those unfamiliar with the genus, Roridula superficially resembles a sundew or rainbow plant, in that its leaves are covered with sticky adhesive threads intended for trapping insect prey. The difference between the two species of Roridula and all other known species of sticky-leaf carnivore is that Roridula secretes resin instead of mucilage as its trapping adhesive, and digestive enzymes can’t pass through the resin. In the wild, Roridula compensates for this with a symbiotic relationship with at least one native species of ambush bug. The plant traps prey which is then fed upon by the ambush bugs, and the ambush bugs reciprocate by defecating on the plant’s leaves. The leaves have special channels intended to capture said feces, so it’s carnivorous by proxy thanks to that foliar feeding. Considering that stories circulate about the larger species of Roridula, R. gorgonias, capturing small birds, both bugs and plants seem to flourish under this relationship.

Not that I’m wanting the ambush bugs (although I’m intrigued as to whether Texas-native ambush bugs, such as our famed wheel bug, might fill the niche), but I’m very curious as to how well either Roridula species might do in Dallas once established. Hence, I ordered a small bundle of seeds of R. gorgonias and sowed them under recommended soil and light conditions. Unfortunately, this was right about the time the drought really set in and the relative humidity came awfully close to negative numbers, so no seedlings. I still have hope, though, that maybe the seeds needed a bit of cold treatment, so the pots remain outside for the winter, and if they don’t sprout by May, then I’ll give it up as a bad experiment.

The real danger is with doing the same thing over and over and expecting different results. As Mark Twain told us, that’s the definition of insanity. That’s also the definition of gardening. Since the cold outdoors is just enough to make me a bit stir-crazy, it was time to put in an order with Silverhill Seeds in Cape Town and see how well the smaller species, R. dentata, might do this summer. Results to follow.
