Penelope Blossom

Penelope Blossom is a recurring character on Riverdale. She is portrayed by Nathalie Boltt.

She is the mother of Cheryl and the late Jason Blossom, as well as the wife of the deceased Cliff Blossom. She is also the grandmother of Jason and Polly twin babies, Juniper and Dagwood.

She suffered severe third-degree burns when running back into Thornhill to save the family portrait after Cheryl set fire to the house in an effort to "start over" with a clean slate. This gave Cheryl the opportunity to control her mother the same way she controlled and abused Cheryl.
