In addition to the 'Sissinghurst Castle' rose, multiple other flowering plants have been grown at Sissinghurst and given names honouring the property or the people associated with it.
Sackville-West herself had low enthusiasm for naming plants in this way, and she and Nicolson actually dug up and discarded a rose that was named 'Lady Sackville' after her mother.
There are numerous plants that have been given trade names based on the gardens, including Tanacetum parthenium 'Rowallane' which has often been mislabelled as 'Sissinghurst', but there are several that are grown at or were discovered at Sissinghurst and were named to reflect the association.

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'.

In 1969, a gardener in Kent bred a cultivar of dwarf bearded iris with reddish-purple flowers.
He gave a specimen to Sissinghurst, where it was planted in the Purple Border, and named Iris 'Sissinghurst'.
During the 1970s, a pink-flowered specimen of Glandularia (Verbena) was given to the garden and named 'Sissinghurst'.
In 1976, the garden was given a distinctive specimen of Pulmonaria officinalis that, unlike the species, has large white flowers (along with the white-spotted leaves of the species).
It was planted in the White Garden and named 'Sissinghurst White'.
Around 1977, the gardeners purchased a collection of seedlings of Thalictrum aquilegiifolium.
They selected the best plant, having larger flowers, and propagated it.
This plant was added to the White Garden and named 'White Cloud'.
From a planting of Penstemon 'Evelyn', which is a selection of Penstemon barbatus, a specimen was named 'Sissinghurst Pink', although Lord does not consider it to be distinct from 'Evelyn'.

In the late 1980s, Pamela Schwerdt and Sibylle Kreutzberger found a specimen of Phlox stolonifera with a remarkably rich purple colour in a florist's shop near the Chelsea Flower Show.
They planted it in the Top Courtyard and named it 'Violet Vere' after Schwerdt's mother, who had been President of the Wild Flower Society and was celebrating her ninetieth birthday.
