I had the opportunity to speak with the person who originally planted the Montbretia back in the early 50's. It was in the landscaping for his architect firm and also at his home. He said they were just plain natural cross of Montebretia....Crocosmia x crocosmiflora. He got the corms from a cousin in Ireland. In the link pics, it shows the small red markings in the throat.
