It's a week or so since I visited Focus so I can't remember exactly. I
think the label may have been "rubus nigra" or "rubus nigrum". I had a
look at wikipedia before posting but couldn't find anything by that
name.

Would you consider the possibility that it was blackcurrant (Ribes
nigrum)?

Google finds references to Rubus niger, Rubus nigra and Rubus nigrum;
the occurrences of the last are at least mostly errors for Ribes nigrum.

Hello again,

Sorry for the delay; I was waiting until I had visited the shop again.
They are selling red raspberries and black blackberries separately, so
this is definitely "something else". I have double checked and the
label says "rubus nigrum".

Hope that helps?

That means that if it was a blackcurrant, the error is on the label,
rather in your recollection. Did it also say black raspberry? If so, it
looks like a technically incorrect botanical name is being used.

Perhaps I should have mentioned it earlier, but Ribes has palmately
lobed leaves, and Rubus palmate (compound) leaves, so you could tell
which genus is was from examination of the foliage.
