Daphne x burkwoodii 'Silveredge'

like that a lot, if I will be able to buy it in the UK remains to be seen

Personally, I don't see much of a difference between that one and Carol Mackie other than size on older plants. The one benefit is that Silveredge is definitely easier to root from cuttings. Have you heard of or seen one called 'Golden Treasure'? It's a beautiful Daphne, probably the best looking variegated variety I have seen. It's available in the UK but nowhere to be found in the US

I have not heard of that form but see both Ashwood nursery and Charleshurst Farm nursery list it but neither has it in stock, have asked Ashwood to notify me when back in stock.
