Why are my happy face potentillas turning brown from the bottom up?
I planted them in May and they are now mostly brown with only some green and flowers on the top branches. They are in a 15 x 3 ft bed and all my other plants & shrubs are doing well. Orange rocket barberry, varigeted Japanese sedge and blue fescue. Photos included. I scraped one of the branches and it looks green underneath but most seem dead. Hoping I don't lose them. Any help is appreciated.

Potentilla care includes removing some of the old stems at ground level after flowering. You can cut back the whole plant to rejuvenate it if necessary. Here is more:
