Hmm, there ae so many discriminatory remarks there that I really don't quite know where to start!! I am in the age group that has white hair, am very computer literate, do know what an aspidistra look like, and am a very keen gardener - but am not a TV watcher so would not have seen the questioner not heard the question.
Anyway, to get back to the largest pot plant, that really is a how long is a piece of string question, there are huge hostas, swiss cheese plants etc, which may be competitors - do you want an indoor or an outdoor plant? I have a 12 foot oak tree in a pot, and I am sure there are many others out there with huge pot plants. Glad you are excluding commercial / professional growers such as Kew and other such places, as some of the plants in pots there are just incredibly enormous - including an enormous rubber tree in one stately home conservatory - no idea which, they run into each other after a few dozen visits.
I am very curious as to why you would imagine a person of advanced years would not frequesnt the boards - or was that supposed to be a jokette?
