Gardeners’ Question Time just recommended a black raspberry called Glen Coe. It sounds like a novelty that might be worth trying. This is another interesting fruit developed by the Scottish Crop Research Institute.
James Wong was the panel member who suggested the raspberry because of its very sweet fruit. He mentioned the Brix rating, which I hadn’t heard of before, but it’s used as a measure of how sweet something is and apparently Glen Coe is “off the scale”. It’s thornless too.
I did a bit of digging (figuratively…) and found these suppliers:
Marshalls Seeds
Suttons
