Introducing Iris foetidissima, also known as Stinking Iris, Gladdon, Gladwin Iris, Roast Beef Plant, and Stinking Gladwin. This plant is a species of Iris found in open woodland, hedgebanks, and sea-cliffs, native to western and Mediterranean Europe. In early to mid-summer, the plant produces purplish or yellow flowers, followed by large, impressive pods that split open to reveal clusters of scarlet or orange-red seeds that remain until mid-winter. This plant is easily grown and tolerant, succeeding in most positions in any good soil in sun or partial shade, even in dense shade. Iris foetidissima prefers a moist soil but succeeds in dry soils and, once established, is drought tolerant. This plant thrives in bog gardens and requires well-drained soil containing some lime. Its evergreen leaves are not very hardy and will die back in cold winds, but the rootstock is much hardier and the plant will soon recover in spring. This plant is perfect for woodland edges and often self-sows. Both the species and its cultivar 'Variegata' have gained the Royal Horticultural Society's Award of Garden Merit. Give this unique and tolerant plant a try in your garden!
