Planted these in the fall of 2020. They came up 2021 and we had a very hard freeze that killed all that growth. Some of them grew back half heartedly and some didn't return at all that year. This year most came back up and just as this one was ready to bloom, it looks like it started dying or maybe rotting? in the middle of the stalk? I've never had one do this before? It is in well drained soil, but we have been getting a lot of rain lately. Any ideas what is wrong with it? Will it live? and is there anything I should do for it? I can't remember it's name, something fairy?
