How do I collect seeds from cannas?

GardenGhostJanuary 1, 2013

While many cannas do not produce seeds, some do. Where the flowers are is where the seeds will form once the flowers fall off. You will see green, spiky, round seed pods forming where each flower was. If that canna doesnt produce seeds, the pods will be elongated, oval-shaped. If that particular canna produces seeds, the seed pods will continue to round and enlarge. The pods will dry and eventually theyll split open, revealing big black seeds inside. The seeds are now ripe for gathering. Discard any shriveled, dimpled, tan or white seeds.
