This iris was thought to be a natural hybrid between Iris chrysographes, I. forrestii, and I. wilsonii, but the true species has now been found in China, where it grows in moist areas on hillsides and in meadows. The flowers range from pale to mid violet or blue-purple; however, most specimens of I. bulleyana grown in gardens are pale yellow, surfused with violet, and these should be sold as ‘Bulleyana’. The standards are upright, while the falls droop downwards and are marked with creamy white stippling. This species usually produces two flowers per stem, and the leaves are grey-green underneath. A bit of a collectors plant.
