I think that Roy has made a good point, there are a great many of us
that hang on to old plants out of sentimental reasons, daft innit. Why
not take cuttings from the old plant and then send it off to the great
garden in the sky :-)

I don't think it is daft. It may be a plant from a beloved relative, now
deceased; it may be a plant you bought on a day you want to remember.

When we moved from one side of Gloucestershire to the other it took a
big van to move all my pots and plants, this was in the late winter and
when Spring came I found that the previous owner had very similar taste
in plants as I do and so I had quite a number all the same variety, they
are all living happily together now :-)
I should have put a smiley behind my daft innit comment
