those look old
and in very good condition. Lucky people who have them!
I grew a giant Asparagus Fern hanging from the ceiling in the office and it did spectacularly well. It grew very healthy for several years and never dropped any needles. My guess is that humidity is higher in the office then in residential homes and the temps are warmer and steadier, don't drop at night as much.
soon as I brought it home, it started dropping needles ...even though it was next to east window. I think fluorescent lighting is quite strong in the office: you can read easily.
but at most homes you can't, unless you're next to the windows.
