x Crataemespilus grandiflora is one of a handful of intergeneric hybrids, which results from grafting hawthorn (Crataegus laevigata (syn. C. oxyacantha)) and Mespilus germanica (medlar). The result is a small tree to 10 m high, which has finely toothed, oval or obovate foliage. Two or three single white flowers to 2.5cm across are produced on short twigs in spring. In autumn globular fruits are produced similar to those of the hawthorn, but larger. This is something of a botanical curiosity, though makes an attractive addition to the garden when in full flower.
