Frankly, as a novice gardener I had no idea what a Canna is.
I googled for an image and came across this Canna lover's blog,
"Canna News - A blog devoted to collecting, growing, hybridizing, photographing, documenting and researching the history of Cannas, the only member of the Cannaceae family of plants".

Now I know enough about them to want some, too!
But it's maybe a bit too demanding for a beginner like me?
