Mine just began to emerge a few days ago here in 6a.

Same here--just coming up.

It was a tough winter and I have my fingers crossed that my one very much established specimen and 3 additions will make it through. But having said that there are no signs of life yet. But again they are late risers. I am still hopeful.

I'd just wait a while and see. I've found that most of my perennials are slow to show signs of life this year

Hopefully they'll start waking up soon. I'll give them until beginning of June - if they're not up by then, they're goners. Even the hibiscus are showing signs of life by first week of June up here.

I am in zone 5 and they don't usually start appearing until after mid-May. Be patient.
