Say "hi" to Craig, my pet mutant cabbage.
He lives in the vegetable bin in our fridge. Two weeks ago, he surprised me by sprouting that extra bit - it poked its way out of the cling-wrap! Today, that bit is at least 10cm tall.
You would think that a fortnight is too long to keep a cabbage but Craig is still in top edible form. I'm not going to eat him, though. I want to see how much more his new limb will grow. Fascinating!
