Yes - and they taste different too, don't they?
I was a gardener. As in, started out in accountancy, hated it, wondered about teaching, went on a horticultural course and loved it so became a gardener, so I had access to some quite weird seeds very early on.
The mice LOVE those small pink beetroots, I had to give up.
Some of the Black Russian tomatoes really are very black, but they need a lot of sunshine to achieve it. So it is a bit of a lottery to grow them. I had one very good year and a couple of fairly bad ones.
Those tomato photos were on my 'miscellaneous' thread, so heaven only knows what else you saw, nonu!
