Hello! I live in zone 6a and we had a very hard, nasty winter. I cut 2 of my butterfly bushes back in the fall and left the 3rd as it was (I kind of forgot about it, it's off to the side of the property). None of the 3 have any signs of spring growth on them. I think things are coming in late this spring because of how cold it is, but seriously nothing green at all. Any chance they will come back or should I just dig them out (they're all quite large and mature) and call it a loss?
Thanks for any advice!
