Rose Blossom

"Such a shame. Your wedding was the last thing I was living for. I lost a grandson, but you, you've lost the love of your young life. Poor child"

- Rose to Betty

Rose Blossom is a character on Riverdale. She is portrayed by Barbara Wallace.

Rose is the grandmother of Cheryl and Jason Blossom.

Early life
Fairly little is known of Rose's early life. What is known, is her affection for Polly Cooper. She took a liking to Polly as the young lady dated Jason, her grandson. At some point during their relationship, Rose gifted Polly with a ring that had been in the Blossom family for generations.

Season 1
Betty Cooper and Jughead Jones attended Jason's memorial, hoping to learn why he would want to escape his family. In effort to find possible clues, the two teens crept into his bedroom, unbeknownst to either of them that Rose was in Jason's room as well. However, she mistakenly took Betty for her older sister, Polly. She grabbed Betty's hand, and realized that the ring wasn't on her finger. The ring that she had given Polly was a Blossom family belonging that had been with them for generations. She says that it should be kept by Polly's heart at all times, but should Penelope find out, she'd take it from her. Still under the misconception that Betty is Polly, Rose went on to say that it's a shame that Polly and Jason never got married, their wedding was the last thing she was looking forward to. She lost a grandson, but Polly lost the love of her life.
