When discussing his architectural specimens, the American Canna hybridist Brian Williams confided that "These are not the regular cannas most people look for but I find them useful and thought I would offer them in the spring. I use these varieties as a back drop for my other cannas. Tall growing with flowers held high above the foliage, they all of these are 7ft tall and up." Amongst these cultivars he includes Canna 'Katana'.Mr Williams stated, "This canna grows to about 7ft tall with dark purple to maroon leaves. The flowers are a peach color with yellow streaking. It is self cleaning and produces tons of flowers. "
