....Perhaps I should also mention here Earldomensis, named after the home of Mr. Courtney Page, who was Secretary of the National Rose Society from 1915 to 1947.  It was raised in his garden from R. hugonis x R. sericea pteracantha, and introduced in 1934.  It is one of the most beautiful, the flowers frail, perfect and pale;  but it is not easy to grow;  we recently lost our lovely plant in the Royal National Rose Society's gardens, and it is not clear whether we can find a replacement.
