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 (thinking she was Polly)[src]

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

Rose is the mother of the recently deceased Cliff Blossom and grandmother of his two children, Cheryl, and the deceased Jason. She is also soon to be great-grandmother to Jason's unborn twins with Polly Cooper.

Rose moved in with Cheryl and her daughter-in-law Penelope in their new home, Thistlehouse, after Cheryl destroyed their former residence, Thornhill.

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.

Rose Blossom at Jason's memorial

Betty Cooper and Jughead Jones attended Jason's memorial, hoping to learn why he would want to escape his family. In an 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. [1]

Season 1 Episode 8 The Outsiders Rose performs a ritual on Polly

Nana Rose performs a ritual to identify the baby's gender.

Present day; Rose attended Polly Cooper's Baby Shower following the discovery that she was pregnant with Jason's child. Upon her arrival, Nana Rose performed some kind of ritual on Polly to identify the baby's gender by using a purple stone pendulum, which led Cheryl to remark that Rose had dementia as well as "gypsy blood," offered as an explanation for her doing this. According to Nana Rose, Polly was pregnant with twins, a boy and a girl. [2]

Season 2

Executing the Accused


Penelope, Cheryl, and Rose in the dining room

In the days leading up to Christmas, Nana Rose sat at the dining room table with Penelope at Thistlehouse where they were later joined by Cheryl. "Where's Jason's stocking?" Cheryl asked. Unfortunately, Penelope couldn't find it. No matter, there was nothing to put in it anyways. Aligned along the table were candy canes, which none of them were accustomed to. However, it would be a "hard candy Christmas" as they had run out of funds.

Later that night, Nana Rose was pleased to see Cheryl return home with a large Christmas tree, which she later decorated, all the while claiming that she saved Christmas. However, with so little money, Penelope was irate. How were they supposed to pay for it all, Penelope asked. Cheryl suggested that she ask Hiram Lodge for a job, though that would force Penelope to admit that the only skills she possessed was being a terrible mother. So, Cheryl advised her to get creative in the new year. As Cheryl exited the room, Rose told Penelope that she should've drowned Cheryl and Jason at birth, "like a basket of kittens".


Rose telling Archie and Betty about the execution

On the night of Christmas Eve, Rose received an unexpected visit from Archie Andrews and Betty Cooper, who came looking for information in regards to the Riverdale Reaper and his rumor execution. After the Reaper killed the Conway family, a group of townsfolk decided to take justice into their own hands. Betty asked if she was apart of the group when they executed the Reaper for revenge. Rose informed Archie and Betty that she did not attend the execution, as no girls were allowed. She was instructed to stay at home while a group of men took care of the rest. Betty asked where the man was hung. However, she was misinformed as he hadn't been hung. They buried him alive. A proper burial, so to speak. Where did they bury him, the teens wondered. Rose advised Betty, who she mistook for Polly, which she had done before, to ask her grandfather given that he participated in the execution. Rose had a picture of them, smiling at the burial grounds, just under the devil's hand. Nana Rose then called out for Cheryl. Having fell ill, she requested that she be taken to her room.[3]

Physical Appearance

Rose is an elderly woman with a frail body, pale skin, and white hair, with a red streak. Notably, Nana Rose has what appears to be some kind of eye condition, possibly blindness as her left eye is a milky-white color, while her right eye is hazel, and looks perfectly fine. Unsurprisingly, she's known to wear clothing that one would expect an elderly person to wear, such as wool sweaters and long, dark-colored skirts.


Having been diagnosed with dementia, Nana Rose suffers from extreme delusion and memory distortion. At Jason's memorial, she confused Betty Cooper, for her sister, Polly, who was engaged to Jason prior to his death. According to Cheryl, Rose comes from a gypsy bloodline, which she believes allows her to predict the gender of a woman's unborn child, specifically Polly's child. However, Rose later revealed that Polly is having twins, one of each gender which had been revealed during a conversation between Cheryl and Betty. Whether or not this prediction is true has yet to be seen.

Rose is quite accepting when she met Polly with Jason when she gave Jason the family wedding ring. Despite Polly being a "Cooper", she didn't seem to care. As if the only thing that mattered to her is that they both loved each other very much.
