Rasberry Allgold

They are highly thought of raspberries with a lovely flavour. They are also good for freezing and wine making!! I'm pretty sure they are widely available but you could always google a few of your local garden centres and check out their listings.
Good luck and Happy New Year

I checked the RHS plantfinder for you. and sorry, there isn't a Nursery listed in S Wales - however, apart from Maple's advice, how about mail order? I'm sure Ken Muir or one of the other good fruit specialists would have them.
