Hey to all you Canna Lovers!!!!! I really do not know what is going on with my cannas. Can someone PLEASE IDENTIFY what the problem is..... It started growing beautifully, but when it came time to bloom it's flower it opened and done what the pics look like.... It opens stays that way.... It doesn't open it's bloom all the way stays like that a few days ( maybe 7) then it starts turning brown and the unopened petals fall off.....
