Iris rosenbachiana is a species in the genus Iris, it is also in the subgenus of Xiphium. It is a bulbous perennial.

It was first published by Regel in 'Trudy Imperatorskago S.-Peterburgskago Botaniceskago Sada' Vol3 in 1884.^[2]

Iris rosenbachiana is now the accepted name by the RHS.^[3]

Note, 'Iris rosenbachiana var. baldshuanica' is a synonym of Iris baldshuanica.^[4]

Iris rosenbachiana Regel Central Asia This species is similar to Iris nicolai both in cultural requirements and form. The flower is purple with deeper streaks down the side. Height: 10 cm (4 in.). Bloom: March and April.^[5]

Short, early-flowering Juno (Jim Kurtz, 20-MAR-07) Belongs in the 'physocaulon' group of junos(Tony Hall), along with Irises kopetdagensis, leptorrhiza, popovii, nicholai, ?baldschuanica and zaprjagajevii, as well as short thick storage tubers which taper to the tip they have an extra side bulb in addition to the bulb which produces the flowers and leaves. flowers are produced as the leaves emerge, sometimes more than one, the seeds have an aril, rosenbachiana is seperated from I nicholai by its anthers (?pollen colour) both have dark lines down the haft and a prominent ridge. (Peter Taggart (UK), 24-JAN-10) Preferred Habitat: Well drained locations with summer drought. (Jim Kurtz, 20-MAR-07) Grow in stony compost and dust the tubers with dolimitic lime dust. must have plenty of air (Peter Taggart (UK), 24-JAN-10) Native Range: Hissar mountains, Tadjikistan (Jim Kurtz, 20-MAR-07 ^[6]

Iris rosenbachiana Authors: Regel Like I. nicolai, but the flowers deep purple with a glowing orange crest on the falls. Central Asia, in the Pamir-Alai mountains up to 2000m. It seems certain that /I. nicolai and rosenbachiana are no more than colour variants of one species and should be combined under the oldest available name, which is rosenbachiana. ^[7]

Iris rosenbachiana; Native to Central Asia. Light purple in flower with prominent raised butter yellow markings leading back into the throat of the bloom. The flower, reaching 100mm in height has a deep sweet scent. Strong leaf growth is beginning to appear and expand. first=Robyn last=Drinkwater title=Two early Juno’s date=March 16 2010 url=http://stories.rbge.org.uk/archives/tag/weekly-highlights+march/page/3

flower until February or March. This species is, unfortunately, as rare as it is beautiful. It comes from the mountains of Turkestan and is a true Alpine plant. That is to say, that it fl owers as soon as the foliage pierces the soil, and the pace at which the flowers develop when once the broad, nipple-shaped sheath of the leaves has appeared above the surface is simply amazing. In a few days the gorgeous flowers are fully developed and stand 4 or 6 inches high on their long perianth tubes. In colour the plants are very variable, one of the commonest forms having flowers of white and crimson, with a raised golden crest on the falls. The leaves only develop later in most forms but it is then clear that the plant is a true Juno Iris, producing its flowers from the axils of the leaves. Unfortunately, my experience, and I believe, that of others, has been that I. Rosenbachiana increases very slowly by offsets. My present plants have all been raised from seed. This is a slow process, taking about four years, but when at last the flowers appear the trouble is well rewarded. Like many other plants in which increase by division is slow, seeds set with some freedom if the flowers are protected from wet, which, of course, destroys the pollen. The capsules, also, contain as many as 80 or 90 seeds, though these do not, unfortunately, germinate very easily. They often lie dormant for several years and then suddenly germinate. Many attempts to hybridise I. Rosenbachiana have been made and have failed, and I believe they are doomed to fail until some other members of the group to which this Iris belongs are introduced into cultivation. All the Juno Irises that we have at present, except I. Rosenbachiana, belong to one or other of two groups, which have never so far been crossed, and it is therefore not surprising that this exception, which is totally distinct from both groups in its seeds and the shape of its falls, should refuse to hybridise with the members of either. Possibly I. Rosenbachiana stands entirely alone, http://beardlessiris.org/reviews/dykes%20on%20irises.pdf Dykes (find other ref later)

Iris rosenbachiana is from Central Asia. Flowers are a deep rich purple with a bright orange crest. Photos by John Lonsdale, Bob Nold, and Jim McKenney who writes: "Here it is blooming in my USDA zone 7 garden in late March, 2006." John Wister, in his 1948 book Bulbs for Home Gardens wrote: "The first of this group (juno irises) to bloom is I. rosenbachiana, coming as early as February in Washington (D.C.)" ^[8]

Iris rosenbachiana Classically this juno section species is thought of as white with deep-violet marks on the falls, and a central orange crest, but it is in fact proving to be variable through yellow to purple and even red. It always has yellow-orange pollen. Our stock contains several colour forms and shows the full and beautifully varied range of colours possible within this species. Cultivated bulbs, raised outside, against traditional advice! Flowers as early as January. ^[9]

in Tajikistan in early April. The plan is to visit the mountains around and east of the capital on the edge of the Pamir and then some areas to the north in the Fan Mountains.
