Veteran actress Polly Bergen -- a.k.a. Stella Wingfield on "Desperate Housewives" -- died Saturday morning at the age of 84.
Bergen passed away around 11 AM at her home in Connecticut from natural causes ... according to her rep -- and was surrounded by family and her longtime manager.
Bergen's career launched in the '50s when she appeared in a Dean Martin/Jerry Lewis flick ... and since then, she starred in many TV shows and movies -- including the original "Cape Fear."
She also famously played the part of Mrs. Vernon-Williams in the cult Johnny Depp classic "Cry Baby."
In lieu of flowers, her rep says donations can be made to Planned Parenthood.
