R. 'William R. Coe'
R. 'William Rogers Coe' (not registered)
The Dexter hybrid 'William R. Coe' is listed (registered) in The International Rhododendron Register, 1958. It is named for the senior Mr. Coe, William Robertson Coe. Synonyms for the name are W.R. Coe and Mr. W.R. Coe.
Another Dexter hybrid was named after Mr. Coe's eldest son, William Rogers Coe. This plant has not been greatly propagated or introduced into the trade.
As the chance for confusion among the various names is so great, we cannot register any other than 'William R. Coe'. However, it is important that we are able to differentiate. the two plants. Their descriptions follow.

NOTE: Late comment from Dr. Herbert Racoff, Columbia, SC: "The plant registered as 'William R. Coe' has been widely distributed in the east. In the channels of trade it is sold and swapped as Mr. W.R. Coe...in my opinion William Rogers Coe is one of the best Coe-named Dexters. When I made a slide of it a few years ago, the blooms completely covered the plant."
