How large do you think a rosebush can grow? According to the Guinness Book Of World Records, the rosebush that holds the record for the largest rosebush is in Tombstone, Arizona.
When Henry and Mary Gee left Scotland as newlyweds and made a home in Tombstone, Arizona, Mary's parents sent some things from her homeland to help her make a new home so far away. They included cuttings from the rose in their yard and Mary planted them. That was in 1885.
Today a strong, gnarled trunk supports a vigorous rosebush suspended by a wooden arbor and the rosebush covers over 8,000 square feet.
I have been there a few times and walked under the gigantic umbrella of roses and walked up steps to look down on the entire spread. This picture is one I took and I have the photos with me. Inside the attached museum, I purchased a cutting and took it back to California, planted it, and the very next year there were some roses and each year my rose bush grew and I took cuttings from it and shared with others. It was the fastest growing rosebush I ever had.
The rose is a white Lady Banksia.
