| Origin | Not known |
The Siberian Elm cultivar Ulmus pumila 'Hansen' is a little-known American tree of obscure origin, possibly raised from seed collected by the horticulturist and botanist Prof. Niels Hansen during his expedition to Siberia in 1897. [1]
Description
Very similar to the species.[2] A specimen planted in 1978 at the Sir Harold Hillier Gardens in England had attained a height of 8 m by 2002.
Cultivation
The tree's current status in North America is not known; at least three mature specimens survive in the UK. Significantly, it is not listed in Green's digest of elm cultivar names published in 1964, suggesting a rather belated introduction to commerce. [3]
