I am looking for tall varieties that are also aggressive spreaders.
I don't have a lot left to trade but I can do postage I do have 1 Musa basjoo pup left right now for trade.
I have just what your looking for! Canna Musafolia aka "banana cann". It spreads quicker than I can trade them from a HUGE rhyzome and gets very tall. Mine were moved to our new house this year and are already 7' tall in spite of being in less than full sun.
