Resilient and mysterious Rose withstood the devastation of Hurricane Katrina and later flourished across the United States.

Peggy Martin of Gonzales, Louisiana, drew attention to a remarkable plant that survived the devastating floodwaters on her former property.

A mysterious climbing rose, later named the Peggy Martin Rose, became a symbol of hope and resilience after surviving the devastation of Hurricane Katrina. Found in Plaquemines Parish, Louisiana, where the Mississippi River meets the Gulf of Mexico, the rose withstood the storm that caused an estimated $125 billion in damages in 2005. Peggy Martin had planted it in her Phoenix, Louisiana, garden back in 1989 after receiving it from a friend. While its true lineage remains unknown, Martin believes it could date back to the 1800s, possibly originating in Europe. Despite her years of research and travel, its ancestry is still a mystery.

The rose drew worldwide attention when it was discovered to be the only plant out of Martin’s 450 antique roses to survive Katrina, even after being submerged in floodwaters for weeks. Dr. William C. Welch of Texas A&M, who had taken cuttings before the storm, was unable to identify it but helped spread it across the U.S. His colleague, Dr. Greg Grant, explained its survival through its exceptionally hardy genetics. Similarly, Charles Shi of the Royal Botanic Gardens, Kew, described it as an heirloom rambler with broad tolerance, likely closer to wild roses than modern hybrids. He suggested the rose may carry traits of Rosa banksiae, known for its toughness and adaptability.

Botanists attribute the rose’s survival to several traits: a rugged constitution, the ability to cope with saltwater stress, and a low-oxygen metabolism that allowed it to rely on stored sugars. It also had the capacity to regenerate quickly, sprouting buds and roots from damaged stems. These qualities made it unlike any other rose in Martin’s garden, where even bulbs and other antique varieties perished.

After the storm, the Peggy Martin Rose spread widely as nurseries began to sell cuttings. It earned the reputation of being “the great beginner’s rose” because of its ease of growth and striking spring blooms. During the Covid-19 pandemic, a nursery in Alabama showcased it on Instagram, sparking renewed interest and even inspiring an annual “Peggy Palooza” festival that now draws thousands of visitors. Today, there are estimated to be hundreds of thousands, if not millions, of Peggy Martin roses grown across the U.S., all originating from Welch’s early cuttings.

In April 2007, Martin’s namesake roses were in full bloom on the tractor shed at her former home.

The rose has since been featured in books, children’s stories, and even social media movements such as #ShowUsYourPeggy, where proud growers share photos of their blooms. Experts like Shi hope to one day add it to Kew’s collection, recognizing its cultural and symbolic significance. While its true identity and original name may never be known, DNA testing has so far shown no exact match to other roses. What is certain, however, is that the Peggy Martin Rose has become more than just a flower it stands as a living emblem of survival, renewal, and the resilience of the people of New Orleans.
