Can you help identify this perennial?

This is just starting to flower. Leaf structure reminds me of Sedum, but it isn't. I am pretty sure it's a perennial. Any ideas?

 

I would have guessed a sedum. There are lots of kinds - are you sure that it's not?

Sorry!

 

Looks like the showy stonecrop (Hylotelephium spectabile, formerly known as Sedum spectabile) that has been growing in my back yard for over 20 years.
The flowers are a favorite of honeybees and butterflies.

 

Yes that's the one! Hylotelephium spectabile
Thanks!!!
