Iris willmottiana is a species in the genus Iris, in the subgenus Scorpiris. It is a bulbous perennial. It was collected from Bokhara in Eastern Turkestan in 1899, by a plant collector on behalf of the Van Tubergen nurseries in Haarlem, the Netherlands. It was then sent to Michael Foster who then first published and described it in the 'Gardeners Chronicle' of London' in 1901. He named it after Ellen Willmott, a renowned gardener. It is one of 60 or so plants named after her. Mr Foster chose Mrs Willmott due to her interest in irises. Iris willmottiana is now an accepted name by the RHS.
