I've definitely had my own surprises. A couple of years back we had tomato plants growing like bushes, we could not eat them all, the dog helped himself to heaps and still there were too many.

Then there's also the courgette plant that would pump out a new one every couple of days for what felt like months, we got so sick of them. Then one day it died, like really died, the thing flattened and went brown and was pretty much gone in a couple of days. It didn't do living or dying by halves.
