Propagation: Propagate Canna plants by division or seeds. Division is easiest. Divide the clumps in the fall, making sure that each Canna division has an eye. Plant the eyes in small plant containers and water them thoroughly. With seeds, soak them in water for one to two days, and the Canna seeds should germinate in one to two weeks. Keep the seeds at about 70 to 75 degrees. Scratch or nick the Canna seeds to damage them – this will help with germination.
