Abstract

Putative hybrids of P. floribunda (Pursh ex Sims) Benth. and Hook, and P. japonica (Thunb.) D. Don ex G. Don were produced but most were short-lived. Morphological traits of 4 of these surviving hybrids were intermediate to the parent species; the hybrids also were sterile and lacked merit as cultivar selections. P. phillyreifolia (Hook.) DC. failed to cross successfully with either P. floribunda or P. japonica.
