Gardening- do our choice of plants reflect our personalities?

I was with a group of friends this morning in our local gardening centre stocking up on bedding plants when I couldn't help but notice that our trolleys laden down with plants reflected our personalities: the smallest in the group had picked all small plants, the tallest had tall elegant plants, and so on .... has anyone else noticed the resembalance between people and their choice of plants? ( our ages ranged fro early 60s to mid 80s).
