It’s funny, as a couple of months ago on the “veg in the city” course at walworth garden farm the same subject came up when someone asked were the green fruits on the potato plant edible. Well the answer was a massive ”NO!” seeing that the potato is in the same family as deadly nightshade and I’ve just looked on the net and it says the potato fruit as well as the plant itself contains large amounts of solanine which is a well poisonous alkaloid.
I should have nipped out the flowers on the plants when they were on their way out so all the goodness would have gone back into the plant to make it’s tuber (ie. the humble potato) rather than making the fruit. Stick to eating the tubers!
A big shout to Scarlett for the useful bit of info on the fruit.
