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]

Roseanne "Rose" Blossom is a recurring character on The CW's Riverdale. She is portrayed by Barbara Wallace.

Rose is the mother of late Claudius and Clifford Blossom, both of whom were killed by her daughter-in-law, Penelope, with poison. She is the grandmother of Clifford's two children, Cheryl and Jason, the latter also being deceased. She is also the great-grandmother to Jason's and Polly's twin babies, Juniper and Dagwood.

Rose moved in with Cheryl and her daughter-in-law Penelope in their new home, Thistlehouse after Cheryl destroyed their former residence, Thornhill. Rose, the rightful owner of Thistlehouse, soon became victim to Claudius' and Penelope's schemes, first being poisoned with tannis root, followed by being pushed, at least according to Cheryl, down the stairs leaving her in a critical state in the hospital. She's since recovered enough to be released from the hospital and remains at Thistlehouse, under the ever-watchful eye of Claudius.

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.

Throughout Riverdale

Season 1

Secret Engagement & Given Blessing

Season 1 Episode 5 Heart of Darkness Rose 2

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.

It was shown via flashback that Nana Rose gave Jason her blessing to marry Polly, however, as revealed in a previous episode, her blessing was not the only thing she gave Polly and Jason, she also gave them her heirloom ring. Present day; Rose attended Polly'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]

Although Rose's son Clifford claimed that Jason had threw the "heirloom ring" at him in dispute, it was unveiled that Clifford had murdered Jason and taken the ring from him. Cliff then committed suicide after his downfall.[3]

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 rumored 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 a part 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, whom 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.[4]

A Long Lost Son


Nana Rose, Penelope, Cheryl and Toni at the will-reading

Rose attended the will-reading upon learning that Clifford had a secret will that he requested be kept secret until after the authorities had concluded their investigation of his drug dealings. Also in attendance was Cheryl, Penelope, Betty, Polly, Hal Cooper, Toni Topaz, aunt Cricket and uncle Bedford, amongst others. Clifford's first declaration was that ownership of Thistlehouse remain in her name. With Penelope, Clifford left ownership of Thornhill, which Cheryl, had burned to the ground. Not that anyone knew this other than Cheryl and Penelope. Regarding the other guests who had been contacted per Clifford's request, they were to receive half of his remaining assets of his fortune. The first half would be distributed equally to anyone in town who could prove with medical authentication that they were of Blossom blood. The will-reading was then interrupted by Alice Cooper. Who came to confront Hal over him asking for a divorce for the sole purpose of cutting her out of the will. Once Alice turned her attention towards the family and began calling them inbreds, Penelope requested that she leave.


Rose and Claudius

The second half of Clifford's fortune would go to Cheryl alone as Jason was no longer with them. And so Cheryl approached the podium with a speech prepared. As the one, true Blossom heir, she felt it was her duty to say a few words. However, Cheryl's speech was interrupted by the return of Claudius Blossom, Clifford's twin brother and Rose's estranged son. Cheryl fainted at the sight of who Cheryl believed to be her father. By the time Cheryl woke up, the will-reading had long since ended. Claudius explained why he had runaway so long ago, which left Rose heartbroken. When he and Clifford were boys, they were inseparable. But it became apparent that Claudius was being primed to inherit the Blossom empire. Until their 14th birthday when he and Clifford were down by Sweetwater River and he pointed a rifle at Claudius and told him about the Blossom curse. How one of the twins always met a violent end and often at the hands of the other. Fortunately, he spared Claudius. But that very night, Claudius ran away from home without a trace and later joined the Merchant Marines where sailed the seas desperate to outrun the Blossom curse.


Blossom family dinner

The following night, Rose had dinner with Penelope, Claudius, Cheryl, and Cheryl's friend, Toni. Penelope suggested that Claudius ignore Toni as she had assumed that it would be a family dinner. But Claudius didn't mind. He even told them about his journeys as a sailor. During one particular journey, he came upon an island. It was the most beautiful and natural place on earth, he claimed. It was named "Lesbos", in reference to Cheryl and Toni's relationship though Rose failed to catch this and was worried that he would be leaving town again. But Claudius announced that he would be staying in Riverdale to assure that Rose and the house was well cared for. Penelope reluctantly invited him to stay in the room over the garage which was freezing in the winter and boiling in the summer.[5]



Nana Rose and Claudius

That morning at the breakfast table, Cheryl claimed that someone was trying to break into her room the night before while she was sleeping. However, Penelope dismissed her claims as she insisted that Cheryl was merely imagining things. On more important note, with Claudius in town, at least for the time being, Penelope suggested that they start considering him to take Nana Rose's stewardship of the syrup business. However, Rose refused to even entertain the notion, and so Claudius offered Rose some of Penelope's special blended tea to calm her.


Nana Rose unconscious at the bottom of the steps

That night at Thistlehouse, an ambulance had to be called after Nana Rose suffered a terrible fall down a flight of steps. Fortunately, she would fully recover. Claudius and Penelope claimed that she suffered from Sundowner's Syndrome, causing her to lose her senses at night fall, which must've resulted in her fall.

Later in the week, she laid unconscious in a hospital bed at Riverdale General Hospital while Penelope, and later Cheryl, spoke to the doctors. They'd be keeping her for observation for another day, then she would be well enough to return home.[6]


Rose watching Penelope lie to Veronica, Toni and Josie

Toni, Josie and Veronica barged into Thistlehouse demanding to know Cheryl's whereabouts. When Penelope refused to answer, Josie threatened to have her mom tell the Sheriff about Cheryl's disappearance. Looking to avoid drawing any further attention, Penelope complied. Rose sat quietly and watched as Penelope fed the girls lies. She told them that Cheryl had started to exhibit strange, deviant behavior. So, she was sent abroad to a private wellness institute where they were trying to help her. In case they didn't believe her, Penelope gave them a drawing of Cheryl's that depicted her and Josie together, which strongly resembled the drawing that Chuck Clayton had supposedly drawn of Josie. This meant that it wasn't Chuck who threatened Josie and sent her a pig's heart, rather it was Cheryl, who had grown obsessed with her. Penelope claimed feared that Cheryl would either hurt Josie, herself or both of them.


Nana Rose calling Toni

The following day, as Penelope was heading out for the evening, she told Rose to behave herself. She had been fed and taken to the water closet. If Rose had to go to the bathroom while Penelope was gone, she was instructed to hold it. In the meantime, Rose was to watch her programs. As Penelope exited Thistlehouse, Rose pulled herself up from her chair and crawled on the floor until she reached the phone. She then called Riverdale High School and asked for Toni. Rose told Toni that Cheryl wasn't far away. In fact, she was with the Sisters of Quiet Mercy. Unfortunately, before Rose could properly inform Toni, Claudius cut the phone cord.[7]

After Cheryl had been rescued by Toni from the Sisters of Quiet Mercy, she vowed to get revenge on her mother Penelope. Her mother refused to let Cheryl partake in the school's musical, so Cheryl decided to channel her inner "Carrie White" and douse herself in blood. Penelope was disturbed at the sight of Cheryl in blood and holding a candelabra, who was threatening her in regards to Nana Rose, claiming to Penelope "I'll end you" if she ever harmed even a hair on Rose. Cheryl proceeded to banish Penelope and Claudius from their home, leaving Rose to Cheryl's care.[8]


Rose is Cheryl's legal guardian

Cheryl has called attorney McCoy over to Thistlehouse to finalize her emancipation from her mother. Nana Rose is now Cheryl's legal guardian, meaning Cheryl's mother and uncle Claduius no longer have any control over her. When Sierra announces her plans to file the papers and send the letter of separation to Penelope, Cheryl volunteers to deliver the letter in person as her mother and uncle are staying on the old Thornhill estate, in one of the barns. Cheryl arrives at the barn to find her mother and uncle in the middle of a clandestine meeting with Hiram Lodge. Cheryl gasps, which Hiram, Penelope and Claudius all hear. Penelope checks outside to investigate, but she sees no one, though that's because Cheryl is hiding in one of the barrels.[9]

Season 3


Nana Rose and Cheryl agree to house some of the escapees

Nana Rose and Cheryl are called over to the Five Seasons by Betty, along with Fred and Sierra to discuss with them the patients from the Sisters of Quiet Mercy, who have been orphaned. While Betty has been housing them, that has become untenable. So, she’s called them over to ask for shelter just until the Sisters testify against Hiram Lodge. Fred agrees to take in some of the boys since he has the room now that Archie is gone. Rose also agrees. She’s saved many children from there before and will gladly do so again. With that, Nana Rose and Cheryl will board some of the girls at Thistlehouse. While all Sierra has to offer is a pullout couch, she agrees to take in a couple too.[10]


Toni, Cheryl, Nana Rose, and Betty at Claudius' funeral

After discovering that Claudius had died while in his cell, the Blossoms hold Claudius’ funeral at Thistlehouse. Rose, Penelope, Cheryl, and Toni are in attendance. At the podium, Penelope states that Claudius was never welcomed to Riverdale and that this is likely why he killed himself. Betty takes a seat next to Nana Rose, who is unconvinced by Penelope’s supposed grief, calling her out for having "crocodile tears".[11]

While trimming the flowers outside Thistlehouse, Nana Rose is approached by Cheryl who is in search of Toni. Rose hadn’t seen Toni since she gave her an envelope of money for rent.[12]

Nana Rose wakes Toni up to warn her that the hunt is afoot at the Thornhill Nature Preserve, and Archie, Betty, Veronica, and Jughead are the hunted. It’s up to Toni to save them, but first, Toni must save Cheryl.


Nana Rose tells Cheryl and Toni about the hunt

Just outside Thistlehouse, Toni has rallied the Pretty Poisons and Southside Serpents in preparation to storm the Farm and retrieve Cheryl. Much to their surprise, Cheryl has already escaped. She joins them, handing Juniper off Peaches 'N Cream, who hands her off to Nana Rose. Cheryl runs into Toni’s arms and they kiss. Cheryl asks where is Betty. Nana Rose replies that she’s being hunted at Thronhill with all the others. Penelope has been planning this for weeks. It’s the grand hunt. With little time to spare, the Poisons and Serpents ride out.[13]

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 was having twins, one of each gender which had been revealed during a conversation between Cheryl and Betty. This prediction later came true although the means in which Rose managed to make this prediction remains unknown.

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.

Despite not having many scenes together, it is implied Rose cares greatly for her grandchild Cheryl, after having informed Toni Topaz of Cheryl's whereabouts after she was admitted to the Sisters of Quiet Mercy by Penelope. She immediately in a lucid state agreed to house some of the Sisters Of Quiet Mercy escapees, showing disdain for that place despite adopting her future daughter-in-law Penelope from there.
