C. 'Roi Humbert is the result of an F2 crossing, namely C. 'Madame Crozy' x C. flaccida produced C. 'Italia', then C. 'Madame Crozy ' was crossed with C. 'Italia'. This reinforced the characteristics of the Italian Group, as the cultivars derived from the C. flaccida cross have subsequently been named. Its rhizomes are heavily marked with maroon and have the shape of the C. indica side of the family, as do the leaves. The colour of the flower comes from the Crozy side, but the petal form is heavily influenced by the thinner and larger C. flaccida blooms.

At the time of its introduction, the breeder C. Sprenger claimed that "Roi Humbert will surprise the horticultural world". Subsequently, it prided a chimera mutation, called Canna 'Yellow King Humbert', that has surprised the world. Did Sprenger know about the potential of such a mutation? The cultivar is a triploid, confirmed by (Dr Khoshoo). It received the ultimate award from the RHS, the Award of Merit (AM) in 1909.

Canna 'Musaefolia' cultivars belong to the Foliage Group of Cannas. In the first work devoted to Canna, Le Canna - authored by M. Chaté in 1867 with the co-operation of Monsieur Théodore Année, we were provided with the first written description and details of origin. The Musaefolia members of the Foliage Group consist of a specimen that was accepted as a native species of Peru by the experts of the time, and at least 7 hybrids and cultivars carrying that parentage. The original "species" was unique because it was without rhizomes, and required to be kept constantly growing. No such species is known to exist in this age, and leading authorities treat C. musaefolia as a synonym of C. paniculata.

Pierre Antoine Marie Crozy

Pierre Antoine Marie Crozy (1831-1903) [also called Crozy aîné—French for "elder"] was a nineteenth-century French rose breeder. He was a partner in the French firm, Avoux & Crozy, La Guillotière, Lyon, actively breeding roses from the 1850s to 1860s. From the early 1860s until his death in 1903 he was also hybridising Canna species, and introduced many hundreds of new cultivars. The largest Canna Group today is still called the Crozy Group, and many of those cultivars are still being raised.
