Canna 'Roma' is one of the most misnamed and misidentified cannas of which I am aware.

It is often identified as 'Britannia', 'Italia', 'Yellow King Humbert,' and 'Florence Vaughan,' as well many others, all of which are totally different cannas.

Personally, I have trialed the 3 most "alike" -- Britannia, Roma, and Cattleya -- and have found distinctive differences in their blooms, rhizomes, and leaves.
The flower colour may vary on Roma to look like the others, but it has rarely done this in my garden.

The most distinctive difference is that 'Italia' has always a solid red lower labellum with a "notch" or hare-lip on the lower edge.
