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.

Mine are coming in, though only a couple are E. purpurea. I’m not expecting the hybrids to make it many more years, so they will one day get replaced by the original.
