My neighbour asked me about this rhododendron at the Parks Board Office right at Lagoon Drive, with such nice brown leaves. I don't think she even mentioned the white flowers, which now are pretty much finished. I don't know why she wants the ID, and I told her that would be impossible. But I'd like to clarify that the leaves are supposed to be green, is that not the case? The leaves at the back that are fully shaded are green. The brown colour is sunburn? I checked the Parks Board document at https://vancouver.ca/files/cov/ted-and-mary-greig-garden-50-rhododendrons-of-interest.pdf, don't see a good match for this. Flowers seem to be completely white, no splotch. All parts are hairy, but no indumentum or tomentum.
