Mike, there is a Âpossibility of your canna being ÂAmbassadourÂ. Ambassadour grows between 3 to 4 ft. on green foliage. It is generally considered a cream white. The flower buds are cream yellow and the blooms often open and blanch to a light cream white. Many of the web photos of this cultivar tend to show a white bloom but this is not the typical result. The labellum on your plant shows more coloration than we typically find in Ambassadour. Good luck. Kent.

My ambassadour is that color for the one I grow in shade most of the day
