One of the (few) things we were happy to inherit "as-is" when we bought our house was the back garden. It was landscaped really nicely and came complete with raspberry bushes! It's only June but we have already had a good amount of raspberries (I would say at least a pint and a half...if you don't include the ones we snack on while "harvesting" :) ). I hope that they keep on coming because they are SO GOOD.
Raspberries grow sort of like Benjamin Button - they start off all dry and light coloured, and then plump up and become nice and tender and beautifully red and plump!
