Ulmus pumila 'Chinkota'

The Siberian Elm cultivar Ulmus pumila 'Chinkota' is from a seed-produced line of extremely cold-hardy and drought-resistant trees raised in the United States. The tree was developed from seed of the cultivar 'Dropmore' by the Horticulture & Forestry Department of South Dakota State University after World War II [1]

Description

'Chinkota' is distinguished from 'Dropmore' by its lower branching habit and earlier dormancy .

Pests and diseases

See under Ulmus pumila. Lime-induced chlorosis is not a problem with this cultivar.[2]

Cultivation

'Chinkota' was extensively trialled during the 1950s in the northern central states of the USA 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.

gollark: As you can see, it is not possible to escape.
gollark: We had to temporarily disable calculus while patching that. Very not ideal.
gollark: Even though it was temporary, the damage to the fabric of reality was substantial. Though not as bad as when someone somehow set all the derivatives of position to 1.
gollark: Specifically, "not finitely describable" is not well defined.
