Kieran Healy of Tucson, AZ is alarmed:
The Triffid: Because I have no talent for or interest in it, I have been putting off dealing with my garden—-or yard, as we say in America. Although the landscaping is now on the domestic agenda, it may have been a serious error to wait so long. Because, over the past few months, this... thing... has grown up with astonishing rapidity by the side of my house, next to the A/C unit. It has become known as The Triffid. It is now about ten feet tall. Here’s a set of pictures showing its leaves and little tubular yellow flowers in more detail. It has recently acquired a little brother a few feet away.
For those of you who don’t know, I live in Tucson. Given how little water we have falling out of the sky around here, it disturbs me that anything so ugly could grow quite so big, quite so fast. (I feel the same way about Phoenix.) My question to the more horticulturally informed amongst you is, What the hell is it? And when the answer is, inevitably, “Giganticus Weedus Noxiensis,” tell me what combination of axe, chemicals and Wagner will be required to get rid of it.
Air conditioners leak incredible amounts of moisture, even in arid climates like Tucson. This plant has found the one moist spot for acres around, and is responding appropriately.
