Rhododendron discolor has been hybridized with other Rhododendrons 

 in many gardens though I do not know if the progeny has received names. 

 Bean (in Rhod. Soc. Not. i. 191 (1918) ) says, "Several crosses with 

 discolor as one parent have been made at Kew chiefly with such garden

 (Aucklandii) , R. maximum and R. occidentals the last of course an 



Azalea. "
