Hosta Vulcan is one for all the ‘Trekkies’ on here! It has actually turned out to be a better variety than I thought it would be. Initially it seemed a bit weak, but now I have beautiful strong examples. Seems a touch slow to start with, so needs moving on gradually, but it has a reasonable substance and is stable, I rarely find any plain green reversions in it. There are not many good white centred Hostas, but this is one of them!
