When I worked at my Garden Center, my boss at the time was famous for her ability to kill houseplants.
Any time we found a half-dead plant either in the Atrium or out in the nursery yard, it would end up on her desk. ;)
(She had a good sense of humor!)
I shared a desk with an office mate who had a perfect green thumb, while I had the passion to have plants while afflicted with a black one. So plants stayed on my side till they were almost dead, then moved to his side to be saved. So people glancing in the office thought that I was the one with the green thumb and he was the ghastly gardener.
