'Crispa' was once to be found in collections in Britain, including Kew, the Royal Botanic Garden Edinburgh, and the Royal Victoria Park, Bath. A specimen obtained from Späth as "U. montana crispa" and planted in 1916, stood in the Ryston Hall arboretum, Norfolk, in the early 20th century. The tree was propagated and marketed in the UK by the Hillier & Sons nursery, Winchester, Hampshire, from 1945, with just 12 sold in the period 1962 to 1977, when production ceased.Only one mature tree is now known to survive in the UK, at the Rosemoor Garden in Devon.
