Cultivation
'Chinkota' was extensively trialled during the 1950s in the northern central states of the US by the USDA's Agricultural Research Service. The tree performed very well, and was recommended not only for windbreak and shelterbelt use, but also as an urban ornamental on the high plains area of Kansas and Nebraska.[2] The cultivar is not known to be in cultivation beyond North America.
