Another amazing Iris from Schreiners welcomed me with its lovely splash of colour for the first time this summer .
Sultans Palace is widely grown commercially in Europe and often offered as part of deal .
It has a wonderful flower shape and strong upright growth .

Like all the other comments say, it's a tough, dependable grower and consistent bloomer for me too. Has a much redder effect in the yard than many newer reds. I would advise everyone to buy it from a reliable source, like Schreiner's, who still carries this and small quantities of many older iris not listed in their catalog. I first bought a package of what was supposed to be "Sultan's Palace" from a now defunct big box store and had four different, older, weedy looking reds show up. I then bought it directly from Schreiner's and have been pleased ever since.

An excellent workhorse iris. Grows and blooms with vigor. Stems are just a little short, but the plant more than makes up for this in the quantity and color of the bloom. Rich, deep red/maroon (the beard is the same color) with golden hafts and a beautful color pattern when looking top down into the bloom.

This one has persisted despite neglect, planting it amongst weeds, etc. Makes a really nice addition to an iris garden.

Description of Sultan's Palace Schreiner's 1977 M 34"
Tailored rich maroon-red self; F. velvety and slightly ruffled; self beard.

Like the cultivor Spartan, the beard should be the same color as the bloom. Too many imposters sold under this name.

This plant has been in the garden since 1991. It has been dug and dragged all over. Forgotten, ignored, through drought and flood and it still survives and multiplies. Naturally it does do better with attention and although it is not among my favorite colors it adds a depth missing with some of the others--it's family!

Rich red blooms on stalks that stand up well to the wind & rain.
