Please help ID these rhododendrons
These rhodies came with my house, and they're gorgeous. I'd love to know which variety they are... Please let me know if you have any ideas. I have read through lists and web sites, and I've identified all of the rhodies and azaleas in my yard except for these.
They're about 7' tall now, and seem to be quite old. The blooms started out very dark pink, and faded to a lovely pink-white as shown in the photos. Hopefully this is enough to ID them.
