'Iris willmottiana' (M. Foster) and 'Juno willmottiana' (Foster) Vved.[1] | |
Iris willmottiana is a species in the genus Iris, it is also in the subgenus of 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.[2] It was then sent to Michael Foster[3] who then first published and described it in the 'Gardeners Chronicle' of London' in 1901.[4]
He named after Ellen Willmott (a renowned gardener). It is one of 60 or so plants named after her.[5] Mr Foster choose Mrs Willmott due to her interest in irises.[3]
It was later illustrated in colour in Curtis's Botanical Magazine tab. 8340 in 1912.[3]
Iris willmottiana is now an accepted name by the RHS.[6]
It is hardy to USDA Zone 3.[7]
Although the plant is quite hardy, in the UK, it is better cultivated in a bulb frame.[5] or Alpine house, but has been grown outside.[8]
It prefers to grow in sandy loam,[9] with good drainage and in full sun.[10]
Iris willmottiana, Iris willmottiana 'Alba' and Iris warleyensis (named after Miss Willmotts garden in Essex), are all easier to find in the US than in England.[11]
The plant listed as Iris willmottiana 'Alba', is now thought to be a white form of Iris bucharica.[7][8]
It can produce hybrids very easy with Iris magnifica and Iris graeberiana.[9]
Habit
Iris willmottiana is very similar in form to that of Iris caucasica. Sharing similar size, shape, leaf margin but having smaller flowers.[3]
It has thickened roots.[8]
It generally grows to a height of between 15–25 cm (7–9 in) tall,[5] in late spring or early summer.[8]
It has about 2 - 6 flowers on a short stem.[12]
The large flowers (about 6–7 cm in diameter),[8] come in various shades of blue, from intense cobalt blue,[10] pale lavender-blue,[13] pale purple,[8] to light purple.[7] The flowers are also blotched with white,[7] and flecked deep lavender-purple,[8] The falls have a large white area and white crest or central ridge with purple marks.[13] The standards are about 1.5 cm long.[7]
It has broad leaves that are glossy lustrous green, that appear in May.[5][8][13] The leaves also have a thin white margin on the edges.[3]
Native
Iris willmottiana is from Central Asia and (the former Russian state),[12] of Kazakhstan.[5][7] It grows wild in the stony foothills of the Pamir mountain range,[5] at around 2900m above sea level.[13] It has been found on Aksu Zhabagli,[13] and Karatau Mountains, in Kazakhstan.[10]
