If you are into the tropical look, don't miss growing the gigantic banana canna. Canna 'Musafolia' has a clouded origin (possibly related to Canna 'Edulis'), but what we do know is that it is one heck of a structural element in the garden. The 12-14' tall stalks are home to extremely large, banana-like leaves...each green with a purple-red border. While Canna 'Musafolia' rarely flowers, the flowers produced are small, red, and really pale in size compared to the foliage...still attracting hummingbirds.
