Why stick to only the traditional things in your garden? Last June was excellent for amelanchia berries - sweet, juicy purple-red berries which look slightly like blackcurrants. The tree itself is fantastic in spring, with showers of starry white flowers, and gorgeous in the autumn with it's burning orange leaves. What more could anyone possibly want?
Also, yellow raspberries -perfect complement to the red ones
And Aronia melancarpa - sinister but great in jam and jellies
