Iris graeberiana is a species in the genus Iris , in the subgenus of Scorpiris. It is a bulbous perennial.
In late spring, [2] (or April), [3] it has between 4–6 flowers per stem and reaches a maximum height of 45 cm (18 in) tall. [4]
It has pale silvery mauve flowers. [4] It also comes in blueish-lavender, [2] or blue-violet shades. [5] The flowers are 6–8 cm (2–3 in) wide with a wavy, [5] white crest on each fall. [2] Which is surrounded by a pale, boldly veined zone. [5]
The white margined leaves, have glossy mid-green tops, but with greyish green bottoms, which are scattered along the stem. [2] The leaves grow to approximately 20 cm (8 in) tall at flowering time, then they extend to twice this. They are between 1.5–3.5 cm (1–1 in) wide. [5]
It was named after Paul Graeber (a plant collector who also collected Iris hoogiana and Tulipa ostrowskiana for the Dutch Van Tubergen company). [6] [7]
It was first published in Botanical Magazine Vol.167 on table 126 by Sealy in 1950. [8]
Iris graeberiana is an accepted name by the RHS, [9] and the iris is recognized by the United States Department of Agriculture and the Agricultural Research Service, since 2003. [10]
It is native to Tajikistan, [11] and Turkestan (parts of the former republic of USSR) in Central Asia. [4]
It is known as one of the more vigorous species, [4] therefore is easier to grow the others in the subgenus. [2] It is also hardy to USDA Zone 5–8. [12]
They are best grown in well-drained soils [13] in open, stony places or an Alpine house, but some growers recommend outside culture, if sheltered from heavy summer rains. [5] The plant attracts birds and butterflies. [14]
It can be seen growing in Le Grand Clos botanical garden in Bourgueil, France. [15]
It is thought to have been bred by crossing Iris graeberiana with Iris magnifica . [12]
