Tulipa urumiensis

Tulipa urumiensis, the late tulip or tarda tulip, is a species of flowering plant in the family Liliaceae. It is a perennial growing from a bulb. By some sources the accepted name is Tulipa tarda. It has a leathery tunic that is glabrous on the inside. It has up to seven linear green leaves that can be up to 20 cm long. The stem is between 4 and 20 cm long. The yellow flowers have white tips, anthers and stamen are yellow.
"Tulipa urumiensis" is native to central Asia, growing in rocky subalpine meadows in the Tian Shan.
It was confused with "Tulipa dasystemon" for a long time, and only scientifically described in 1932 by Otto Stapf and again as "T. tarda" in 1933.
The plant blooms in late April and early May in the Northern Hemisphere. The plant was accorded the Royal Horticultural Society's Award of Garden Merit in 1993.
