I’ve commented elsewhere about Some Guy, because you can always connect the worst advice on the planet to Some Guy. Horticulturally speaking, Some Guy can be blamed for all sorts of concentrated vile, but one of the most pernicious involves spreading tales about effective use of scarlet trumpetvine (Distictis buccinatoria).
D. buccinatoria doesn’t sound quite so bad upon first glance. It’s a very enthusiastic climbing vine, sometimes growing as big around as your leg, with a nearly fernlike thick foliage. Its name comes from its equally enthusiastic blooming habit, with bright red blooms that attract hummingbirds by day and hawkmoths by night. It also sprouts from its roots, growing a thick corky rind around an extremely tough and fibrous root core. If you’re looking for a tenacious and full vine that covers just about anything, you can’t find anything better in the Dallas area.
And that’s precisely the problem. Scarlet trumpetvine blooms lead to long, beanlike seed pods whose contents are gleefully spread by birds, so they end up everywhere. They don’t seem to have anything indigenous that keeps them under control, so while their leaves make excellent shelter for lizards and beneficial insects, they also transpire so much water during the day that any wood underneath them starts to rot very quickly. Since nothing seems to trim back that foliage, that means that fences, walls, posts, and sheds are rapidly buried under thick blankets of trumpetvine.
This sounds perfect if you want trumpetvine to stay, but just TRY to remove it. This is where Some Guy comes in, because the trope going through yuppie neighborhoods is that “you should plant trumpetvine around telephone poles so that it’ll cover the pole.” Not only does this make the local utility reps absolutely loathe you, as reaching the pole, much less climbing it, is impossible when sheathed in trumpetvine, but it also guarantees that the seeds will spread elsewhere. Chop it down, and it readily resprouts from the roots. Mow down the new growth, and chunks will reroot and spread through the immediate area. Spray it with herbicides, and the sprays wash off the leaves and kill off everything underneath. In my case, I made the mistake of letting trumpetvine get established along a wooden fence during the summer of 2011, and I’m still cutting it back every week from the roots from that summer.
Now, Amanda Thomsen of Kiss My Aster repeatedly argues that scarlet trumpetvine is of the Devil. I’d argue that if confronted about trumpetvine, Satan would stand up and profess true innocence, arguing that some things are too foul for him to consider. You could go through other pantheons, and every possible suspect would do the same thing. Loki would swear upon Yggdrasil that he wouldn’t think of doing such a horrible thing. Set would set upon his heels and cry at the accusation. Tezcatlipoca would be found in the bath, repeatedly scrubbing himself with wire brushes. Camazotz would go back to his old cutting habit. Nyarlathotep…Nyarlathotep would just sit back, vomiting silently in utter terror that someone would give him credit for creating or developing scarlet trumpetvine.
This garden season, have some sympathy and some taste. When you’re saturation-nuking the garden to blast out trumpetvine, don’t randomly assign blame for something of such cosmic horror. Instead, just ask yourself “What did those gods of chaos and evil ever do to you to deserve that sort of insult?”
