In the White Garden, "Rosa mulliganii" is trained over an arbour to provide the centrepiece of the design. Several varieties are trained to climb up trees in the Orchard. These include 'Albéric Barbier', described by Thomas as "a great favourite" among the hybrids of "Rosa wichuraiana". Another is 'Félicité et Perpétue', a "Rosa sempervirens" hybrid that was named for the two daughters of the gardener to the Duke of Orléans in 1827, who were, in turn, named after Perpetua and Felicity. A third is the noisette 'Madame Plantier', of which Sackville-West wrote: "I go out and look at her in the moonlight: she gleams, a pear-shaped ghost, contriving to look both matronly and virginal."
