Thanks for this pleasant visit, Mick.....some good plants, eh?
I am not very clued up about this Rhododendron.... the name "Valapsis Group" means nothing to me
Looking at the plant, which has the appearance of a yellow flowered leucapsis, I will make a guess ( only vaguely educated, I'm afraid!) that this "group" is a collection of hybrids of R. valentianum ( small deep yellow flowers) and R. leucapsis ( larger campanulate white flowers) Both species have hairy leaves which are evident in the plant.
If Kaye is reading this, perhaps she can get more info?
