Shirui Hill, with an altitude of 2570 m, is located in Shirui village of Ukhrul District of Manipur. The rare and endangered siroy lily is the state flower of Manipur. Shirui peak (and the lily) are known by different names, each slightly different from the others: Siroy, Shiroi, Sirohee and Shirui, the last one being the local pronunciation. The hill is a part of the Shirui-Kashong range, which is proposed to be a national park under the Wild Life (Protection) Act, 1972. It is one of the only two places in Manipur that the Siroy lily is found, and even here only for a couple of months following mid-May every year. The area is also known to be inhabited by endangered bird species like the Blyth’s tragopan and Mrs. Hume’s bar-backed pheasant or nongyin, Manipur’s state bird.
Such widespread flowering of lilies as is seen today could not be seen between 1994-5 and 1999- 2000, when hardly 3-4 mature lilies were found in bloom. The huge numbers of visitors visiting the area during this season would flatten the beds and pluck and uproot the lilies. This resulted in a sharp decline of lilies in bloom.
