Officially, I have not been growing any Lenophyllum texanum since New Year's Day, 2013, when I threw out the one pot that I had growing, marked it down on the spreadsheet as deceased, and went on.
The plant had other plans. In the process of disposal, some leaves fell off, which I noticed but figured weren't worth the trouble of digging out of the flat and throwing away. Sure, it's a desert plant, but how's it going to survive with no soil, brief periods of water, and little light, was the thinking.
A year and a half later, the leaves have grown into whole plants. The roots have intertwined to form a little mat, against which all the stems can brace themselves, keeping them upright even without any soil. And apparently the mat is good enough at retaining water that they can make do, and even thrive, with just the water they get from being sprayed for about 15 seconds, every couple weeks.
This is impressive, and would even be endearing if it gave the impression of having to exert itself a little. I'm happy to root for underdogs every now and again. But it's not acting like a plucky little underdog, struggling to survive against all odds; it's closer to an unstoppable Terminator type. For the moment, I'm going to keep it -- it's growing in an unused space in the flat, and it's not asking anything of me -- but at least 50% of that decision is because I'm no longer sure whether it's possible to get rid of it.
