p37. Gregg Lowery: 'Mary Washington'. Found in Virginia, USA, at Mount Vernon, George Washington's estate, circa 1891. An apocryphal story suggests that this rose was raised by George Washington and named for his mother. The plant however did not surface at Mount Vernon until the end of the nineteenth century, and Washington died five years before John Champneys introduced his 'Pink Cluster'. Regardless, it is a very beautiful example of the class, having small, very double blooms less than an inch across, which appear in large, full clusters. The plant grows upright to 5 feet and is stiffly spreading to about 4 feet. It makes a tidy and thrifty shrub that is always in bloom.

p44. Barbara Worl: it was at Mount Vernon that I first saw 'Mary Washington'. She was covered in small pink buds that opened into loose white petals. As I admired her, I learned from a discussion taking place behind me that local gardening groups had called the rose "Martha Washington" in the 1920s, but that was eventually corrected as the rose is actually named after George Washington's mother. Later I heard a woman from Florida enthuse about the reblooming qualities of this Old Noisette, so I planted 'Mary Washington' to grow up an iron triptych against a wall in a corner of my garden. There she fills the space beautifully and reblooms with abundance.

p362. 'Martha Washington'. A plant has been grown under this name for many years in the flower garden at Mount Vernon. It is first evidenced in documents dated 1889. This plant can be identified botanical with Rosa roxburghii Trattinnick. Propagations of this plant were sold as souvenirs at Mount Vernon between 1890 and 1900 and again from 1932 to 1935. Commercial nurseries offered plants of many varieties and types between 1890-1900. Among them were: a vigorous climber with flowers and foliage identical with 'Old Blush', a climber with very pale pink flowers of Noisette type and a trailer.
