This is a large-fniited cherry, originated in 1888 by the Russian plant-breeder, I. V 

 Mijurin, at Kozlov, Central Russia, and named " Knyasnaia Sjevera," meaning " Queen of 

 the North." The United States Department of Agriculture introduced it into this country 

 tmder the number 32674. It is claimed to be a hybrid between an early Vladimir and a 

 variety of Sweet Cherry called "White Winkler." It possesses excellent shipping and 

 keeping qualities. This cherry has stood the severe winters of Central Russia very well 

 and may be expected to thrive in parts of the Middle West and where the climate is more 

 or less semi-arid. Tree vigorous, upright, with few side branches; trunk smooth and 

 clean; fruit large, pale red, with a fresh sour-sweet flavor; ripening about the end of 

 June.

The Koslov cherries are seedlings, not a single variety. A number of seedlings were 

 imported by the Ontario Fruit Growers' Association in 1889, from Koslov, Crimea, Russia, 

 where they were grown by Russian peasants, being propagated from pits. The trees are 

 low, bush-shaped, slow in coming into bearing and most of the fruit is worthless. The 

 one most grown is moderately large, roundish, pointed at the apex; suture barely traceable; 

 stem long, set in a slight depression; skin dark red, turning black; flesh dark red, tender, 

 juicy, acid; ripens from the last of July to the last of August.
