It looks great, Dave. The cannas should keep putting up new stems and blooming as long as the weather's warm and you keep feeding and watering them. Give 'em all the sun you can, too.
Once a stem is finished blooming, if you cut it off right at ground level (it's hard at first but it works) this stimulates the plant to put up new growths, and also make more rhizomes for next year!
Be careful, though, sometimes a stem will put up a second bloom scape behind the first one.
