When she first visited the property, Sackville-West came upon a dark red, double-flowered form of "Rosa gallica" growing wild and apparently dating from earlier plantings there. She eventually planted it in the Orchard, and it is now known as the cultivar 'Sissinghurst Castle'. In 1930, even before the deeds to the property had been signed, she planted the noisette rose 'Madame Alfred Carrière' on the south face of the South Cottage, making it the first rose she would plant in the gardens.
