Here in central Europe, I have black and red variants in my garden, from which I've been picking for my daily muesli on the regular for years, and probably have a few bowls' worth in the fridge, as their season is over but my collecting isn't .. they are delightful plants, providing much in terms of vitamin C and other things, such as sugars ..

I think berries (and peas) are among the easier things to grow locally, and I sure wish more people in the cities and things did, we'd have more for the birds ..

Of course, this story is a reason we can't just have 'uncontrolled agriculture' but so, I'd just say let people grow the native species of whatever they can eat and leave us all alone, gardening is a human right ..
