Pages 5-7: Michael H. Walsh in Massachusetts used both R. multiflora and R. wichuraiana [in his breeding program]... In 1909 Walsh introduced Excelsa, a rambler with crimson blossoms… [it] set a new standard for wichuraiana hybrids and it was soon grown everywhere, for it was healthier and easier to train than 'Crimson Rambler' -- the other popular red climber of the day.
