I won't even grow em now!
Everything in my area is flat eat up with canna virus!
Oh yea...those same tropicannas were at my lowes, three kinds, black, white and regular.
ALL OF THEM CAME WITH CANNA VIRUS!
I'm done with cannas for a few years atleast!
If you do use them in containers, don't go too small. 10 gallon minimum if you want nice big plants, they will live in smaller, but you will have to water so much that you just might let em die on purpose!
