How do I grow cannas from seeds?

GardenGhostJanuary 1, 2013

Canna seeds are tough. For best germination, they should be nicked. To nick them, you can use a file, a grinder, or even a drill to drill into the seed a little. You just want to break the hard surface of the seed just enough to see a little bit of the creamy white interior of the seed. After nicking, soak the seed in water for a day or two. You should see the seeds swell as they soak up the water. Then plant in moist soil. Keep the soil moist and warm and your seeds will sprout. If started early, like during winter in a greenhouse, cannas grown from seeds can bloom the first year. However, the seeds from the hybrid cannas do not produce plants like the parent plant. They usually revert back to the small flowered type with traits of both the wild canna and the parent. Once in a great while, you may get lucky and a viable canna will grow from one of those seeds, but it doesnt happen often.
