What was your most unkillable plant ever?
AKA The Plant That Would Not Die?
I had a spider plant handed down from a coworker. I'm not too fond of spider plants anyway, and this one was not attractive. It only grew to one side, its roots were three times the size of the foliage, it had no variegation or anything and as a matter of fact looked motheaten and dusty no matter how well cleaned, and even seemed to be morose about occasionally putting out a few babies on a spindly stem.
When the office moved I took all the plants home and repotted, except for the spider plant. I removed it from the pot, washed off the roots, and tossed it in an empty container with no soil, waiting for it to die before I put it in the compost heap.
It stayed all summer in complete shade, roots bare, half upside down. It collected rainwater and a little hose overspray and the accursed thing thrived. It didn't lose a single leaf, and it put out another spindly stalk of babies.
In the fall I was chatting with a friend who said she loved spider plants so I tossed the stupid thing in a plastic shopping bag and handed it off to her. I have no idea if it is still alive or if actual care has finally killed it.
So that's why I tend more toward 'neglect' in plant care, since apparently they do better when I don't try too hard to keep them alive.
So what's your Plant That Would Not Die?
