I think he has only esplained it ta ME before, cuz I watch out fer plants here.
See this Waxy Hoya? TBT says it was a housewarming gift. In 1982. His sisfur Susie gave it to him when he moved into his first house. It was a rental, but it WAS a real house. So that makes it 30 years old just about this moonth. Not many plants live this long. I guess TBT gives it ezactly the "benign neglect" it likes.
Have you got some long-lived house plant? Will you describe it and give a back-story?
