Canna × ehemannii is an early cultivar of canna, believed to be a hybrid between Canna indica and Canna iridiflora. Its name is sometimes spelt Canna × ehemanii, although it has the English name Ehemann's canna. The name is of doubtful standing, being treated as a "nomen subnudum" by, for example, the World Checklist of Selected Plant Families, meaning that it was published without an adequate description.
