1906. Christopher Lloyd ranks this as one of his favourite Cannas. Its rich, leathery, dark bronze foliage and sunset-orange flowers (‘bright, yet by no means aggressive’) are
Pennsylvania Canna-master Leon Wintzer’s most enduring legacy. 3-5 feet (3, $5.00 – 10, $14.75)
Ian Cooke, The Gardeners Guide to Growing Cannas
(T) Probably the best known of all bronze-leaved Cannas. It bears, soft orange flowers on top of vigorous plants with massive dark-veined leaves. This cultivar was raised by Wintzer in 1906.
Confusingly, the name is sometimes used for any orange
Canna with dark leaves. In Britain, there are at least three different forms available under this name. Probably he most correct is the one that has for many years also be sold under the name ‘Professor Lorentz’. It is very vigorous and makes a tall bold plant sometimes nearing 2·4m (8ft). It is widely available.
Burnt orange blossoms on burgundy foliage. Growth range from 3 to 4 feet.
