I found one that was named Azurem or similar which I was going to order but the postage was almost £20. Didn't mind the £11.99 for the plant itself. Have settled for the regular one and ordered a 1 litre off Ebay in the end for £8 something in total. Will look out for the better one but it is only available from a handful of nurseries on the RHS stockist list.
Very happy to have found out what it was and looking forward to replacing the one we lost. Thank you so much for your help.
