Prunus × hillieri is the result of a cross between Prunus incisa (Fuji cherry) and Prunus sargentii (hill cherry). The most famous cultivar is 'Spire', which was developed from a sport discovered growing in Hillier and Sons nursery of Winchester. Growing to 10 m (33 ft), with at most a 7 m (23 ft) spread, 'Spire's columnar growth form and pink flowers make it quite useful in particular landscaping applications. It is regularly used as a street tree. In 1993 'Spire' won the Royal Horticultural Society's Award of Garden Merit.[1]
