Sackville-West made an exception to her dislike of naming plants in memory of people and purchased "Viola" 'Lady Sackville' late in her life, around 1960, planting it in the Delos. A few years after her death, a seedling appeared that seems to have been a spontaneous cross between 'Lady Sackville' and the variety 'Nellie Britton' that was growing alongside it. It had flowers of a rich pink that were larger than those of the parent varieties. The gardeners named it 'Vita'. Sackville-West had also grown a variety of rosemary ("Rosmarinus officinalis") that self-seeded in the Tower steps, and differed from the common variety in having upright rather than trailing stems, and flowers of a deeper shade of blue. It has come to be recognized as a distinct cultivar, and named 'Sissinghurst Blue'.
