The ones that are still dormant (possibly dead) have been in the ground for 15 years. The root "clump"? is about 8"-10" across in most cases. They are always cut right back & the new growth will reach 18"-24"
I have lost a few over the years & that patch only has fuscias on it, I guess about 30.
They were all hardy varieties, about 6 different if I recall & all grown from cuttings I took from a single plant.
Over a two year period I took over 200 cuttings from those original 6 plants & their offspring, so, not an expensive operation, probably less than £10
I don't have the inclination to dig them all up to over-winter them indoors, the greenhouse isn't big enough
Besides which, it's always full of the non hardy types in pots
I will give them another couple of weeks, but I know that they have always shown signs of life earlier than this before.
It just struck me as strange, especially when you consider the good weather we've had for the past few weeks, that not a single one was coming out to play
