Iris graeberiana is a species in the genus Iris, in the subgenus of Scorpiris. It is a bulbous perennial.
It was named after Paul Graeber (a plant collector who also collected Iris hoogiana and Tulipa ostrowskiana for the Dutch Van Tubergen company).[2][3]
It was first published in Botanical Magazine 167: t. 126 by Sealy in 1950.[4]
Iris graeberiana is an accepted name by the RHS.[5]
It is hardy to USDA Zone 5-8.[6]
It can be seen growing in Le Grand Clos botanical garden in Bourgueil, France.[7]
Habit
In late spring[8](April)[9] it has between 4-6 flowers per stem and reaches a maximum height of 45 cm (18") tall.[10]
It has pale silvery mauve flowers.[10] It also comes in blueish-lavender,[8] or blue-violet shades.[11] The flowers are 6–8 cm (2.5–3 in) wide with a wavy,[11] white crest on each fall.[8] Which is surrounded by a pale, boldly veined zone.[11]
The white margined leaves, have glossy mid-green tops, but with greyish green bottoms, which are scattered along the stem.[8] The leaves grow to approximately 20 cm tall at flowering time, then they extend to twice this. They are between 1.5-3.5 cm wide.[11]
It is known as one of the more vigorous species,[10] therefore is easier to grow the others in the subgenus.[8]
They are best grown in well-drained soils [12] in open, stony places or an Alpine house, but some growers recommend outside culture if sheltered from heavy summer rains.[11]
Native
It is native to Tajikistan[13] and Turkestan (parts of the former republic of USSR) and Central Asia.[10]
