I'm posting this as for Appreciation, not for ID, but if anyone wants to comment on the ID, I would love to know it. I just realize how hopeless that seems to be. Still, I've come up with a suspect: Rhododendron 'Washington State Centennial'. See Paghat's Garden: Rhododendron x 'Centennial'. It's yellow with white, deciduous, frilly petal edges, lots of hairs, some orange on the dorsal petal, from around here. I think this is supposed to be lepidote, and I imagine I see scales at dead centre in the second photo. This is on the Ted and Mary Greig Rhododendron Garden in Stanley Park, where there are a lot of fragrant azalea-type rhododendrons in bloom right now.
Here is a photo of the Rhododendron Path. The deciduous azaleas are getting past their peak now. Here are a few other azaleas, with similar leaves and hairiness. I have no idea if these are all related.
So far I don't think it's 'Washington State Centennial'. But if it were me I'd want to make in person comparisons with live material of known identification on other planting sites, using a cut sample of the plant in question - this procedure can be highly illuminating. And I'd want to confirm a suspected identification with backing information gotten from books and catalogs. Including if 'Washington State Centennial' has been on the scene long enough to be the one in the Greig planting. Otherwise, what information does Parks have? Any planting maps, other pertinent records?
