Weird potato thing

Sorry please excuse my complete ignorance but my first time growing spuds, I'm growing maincrop Desiree and planted them in march they have been flowering for a few weeks now anyway I was watering them this evening when I got the shock of my life I thought there was a tomato plant growing between the spuds but no the flowers have finished and have tomato looking things growing from them  :blink: is this normal?? I had a walk around the site checking other people's spuds but no one else's have them

Can sometimes be known as potato apples. Don't eat them they are poisonous. Some people remove them as it is rumoured to reduce your crop if you leave them. Personally I think life is too short to spend time looking for them and removing them. Potatoes and tomatoes are related hence the similarity.

They'll be fine in the compost
