Origin
England

'Jacqueline Hillier' is a cultivar of the natural hybrid Ulmus × elegantissima Horwood found in the Midlands, England. It makes a small to medium-sized suckering shrub of dense habit, bearing small, double-toothed scabrid leaves 25 mm to 35 mm long on densely-hairy twigs. Resistance to Dutch elm disease is not known, but is probably academic as the shrub is unlikely to attain the size at which it would attract the attention of the bark beetles that act as vectors of the disease. The cultivar originated from a specimen found in a Birmingham, England garden circa 1960. It is commonly found in cultivation in the USA and Europe, where it is considered particularly suitable for low hedges, or even bonsai.
