Iris foetidissima


Iris foetidissima, the stinking iris, gladdon, Gladwin iris, roast-beef plant, or stinking gladwin, is a species of iris found in open woodland, hedgebanks and sea-cliffs.
Its natural range is Western Europe, including England south of Durham and also Ireland, and from France south and east to N. Africa, Italy and Greece.
It is one of two iris species native to Britain, the other being the yellow iris.
It has tufts of dark green leaves. Its flowers are usually of a dull, leaden-blue colour, or dull buff-yellow tinged with blue; the seed capsules, which remain attached to the plant throughout the winter, are 5–8 cm long; and the seeds are scarlet.
It is known as "stinking" because some people find the smell of its leaves unpleasant when crushed or bruised, an odour that has been described as "beefy".
This plant is cultivated in gardens in the temperate zones. Both the species and its cultivar 'Variegata' have gained the Royal Horticultural Society's Award of Garden Merit.
