Phenology:—Flowering: March–May; fruiting: May–August (depending on elevation).

Ecology:—Clayely and stony slopes, rock ledges, among trees and shrubs, in valleys of rivers, near melting snow, in foothills, lower and middle mountain zone, 500–2500 m a.s.l.

Etymology:—Regel named this tulip after K.P. von Kaufman, Russian military leader, who led the conquest and colonization of Central Asia. Since 1867 – Governor-General of Turkestan, commander of the troops of the Turkestan Military District.

Note:—This tulip species is the ornamental plant of the highest importance for selection of garden tulips. Rukđâns (2008) regarded plants from Kazakhstan as separated species Tulipa berkariensis Rukšans (2007: 174), distinguishing from T. kaufmanniana by a lower amount of DNA, spherical bulbs producing 1–2 long stolons bearing vegetative bulblets, and a number of leaves (mostly 2). According to J.J. de Groot’s communication, yellow-flowered tulips from the Uzbek part of the Ugam Range also belong to T. berkariensis .
