Would like to give cannas another try this year. Need help.
Last year I planted 3 canna tubers (dwarf variety) in a huge pot on my deck. They were in full sun. Only one had any growth at all and even that one did very poorly. The leaves were pale and limp looking and it didn't flower. I would love to try a tall variety this spring. I want to put them in the ground, not in a pot. However, I need to know what went wrong last summer. It is possible that I didn't water them enough, but we did have LOTS of rain in June, so I'm surprised that I had no growth from 2 of the 3 tubers. Are there varieties that are stronger than others? I like dark red flowers. Thanks in advance.
