I found some orange-yellow raspberries growing wild in the northern parts of Ireland (Donegal, Antrim, Derry, Fermanagh, Leitrim) last summer.

Never had seen them before.

So I investigated, and learned, that they had been imported for gardens because they are very decorative, and have then escaped into wilderness.

After I learned that they are eatable, I tried them - and found them disappointing - I prefer the pinkish-red "normal" raspberries ...
