The Chinese elm cultivar Ulmus parvifolia 'Golden Rey' is an American clone selected by Oklahoma City nurseryman Bruce Rey in the late 1980s from a chance nursery seedling, and patented by him in 1990.
Chiefly distinguished by its leaves that emerge a uniform light yellow, maturing to chartreuse with touches of salmon pink, and by its spreading dome shape. The exfoliating bark is a mottled mix of grey, orange and brown.
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the elm leaf beetle Xanthogaleruca luteola.
The cultivar has been much planted in Oklahoma City. 'Golden Rey' is not known to be in cultivation beyond the United States.
