This page needs to be updated now on two counts;
Firstly, Princeton Elm which were bred for resistance to Dutch Elm in the U.S have now been shown to be only mildly resistant, with most plantings having failed in the UK. Secondly, Hillier's now have the sole distribution rights for the 'resita-elm' the only Elm to have an unbroken 100% resistance record. They sell this as: Ulmus 'New Horizon' http://www.resista-ulmen.com/en/. Finally, this is a worthy replacement tree which Landscape Architects and Local Authorities can plant with confidence as a worthy replacement for a native species almost entirely lost.
