oh, forgot:
mine are species C. indica, edible Canna; flowers are tiny. Mine never flowered in 3 years, but they are super constricted in 1 gal pots, while normally they are at 5' and spreading like wild fire.
the dwarf hybrid that i got flowered on 3-4 stalks, then produced 3-4 more, etc and keeps going in the same 1 gal pot. I'm taking it to FL for winter for the balcony. It is a shorty, just 18" with blooms from the pot.
It can probably bloom in sunroom too thru winter.
