Rhododendron ‘Virginia Richards’ ([R. wardii x ‘F.C.Puddle’] x ‘Mrs. Betty Robertson’) – A prolific bloomer with abundant trusses of pale apricot and light pink flowers that fade to cream, accented by light reddish-pink spotting.

Rhododendron ‘Cream Crest’ (Rhododendron rupicola var. chryseum x ‘Clipinense’) – This semi-dwarf rhododendron opens to the palest of creamy yellow and fades to cream, usually flowering from April to May.
