The Chinese elm Ulmus parvifolia 'Prince Richard' is an American cultivar raised by Curtis Wilkins in Glen Flora, Texas. Originating as a chance nursery seedling, it was trialled from 1989 and patented in 1998. [1]
The tree is distinguished by its high density branching and dwarf to semi-dwarf size, attaining a height and spread of 2.1 × 1.5 m at five years, with a stem diameter of 4.4 cm. The dense, deep green, foliage on numerous branches affords the tree a rich, full, and rounded appearance. The small oval leaves, acute at the apex, are alternate, simple, with serrate to crenate margins, 3.0 cm long by 1.8 cm wide. [2] Growth is slow, averaging 25–31 cm per annum in south-east Texas.
'Prince Richard' has shewn no more or less resistance or susceptibility to diseases and pests which normally afflict U. parvifolia cultivars. [2]
'Prince Richard' has been listed on both US and European Patent Office sites. The plant is easily propagated by softwood cuttings in a 100% pine bark rooting medium. [2]
