Can someone identify this plant?
Also, how does one propagate this plant to a pot?
This plant grows in Florida.
They're cannas. This is actually a near-duplicate of this question. Cannas have very large rhizomes which, in the Northern US, are dug every fall, stored over the winter indoors, and then planted out in the spring. You would use this same method in a pot, but make sure that the pot is large enough! I would estimate that a seven-gallon pot is the minimum size to use for a canna.
