'Nancy Evans' is a small evergreen shrub only 24 - 36" in height but the unusual characteristic is that the buds start out red and then change to a pale yellow as they open.
From a 'Hotei' x 'Lem's Cameo' cross made by Ned Brockenbrough of Bellevue, WA. So there is a twice local (Seattle area) involvement because 'Lem's Cameo' ('Dido' x 'Anna') was selected by Halfdan Lem in Shoreline, WA. (Lem was also one of the raisers of 'Anna').
Nancy Evans is one of my favourite rhodos, similar to one I grow named Jingle Bells. It was developed by Halfdan Lem who, being born and raised in Norway, would probably have called it 'Yingle Bells'. QBARS - v31n1 Halfdan Lem, Hybridizer
Ah, I see that's from that very enjoyable article. Thanks for the link. I was surprised to find that I recognized the name of one of Lem's rhododendrons that I photographed at VanDusen yesterday ('Pink Walloper', just in bud).
