Verbena bonariensis - is there hope??!
Substantial plants from GC planted in summer 2019, returned in 2020, although no new plants so guess they didn't self seed despite me leaving on the seedheads until spring. I think they had a bad case of mildew which I have sprayed for. They are now looking rather sad and I can't see any green shoots... is there any hope? Or do I need to start over?
