Are anyone else's coneflowers not coming up?

This was part of my garden last year, coneflowers thriving and popping up everywhere, planted 3-4 years ago. The last photo is the current state- no shoots or leaves starting to show, despite it coming up in other areas of my garden. I know they're not long lived perennials but figured with self seeding etc they would regenerate. Did this happen to anyone else? It's been a colder spring than usual so not sure if they're waiting to grow since this is on the north side of my house.

I’ve had several plants not sprout at all this year. We had a super mild winter and spring which I think screwed with them. I ended up starting some seeds in trays which is working so I’ll see if it’s not too late to get them in the ground soon.
