canna lilys - they have a bulb type root system, generally you plant them in ground. there are full ht cannas 6-8 ft and dwarf canna 3-4 ft tall. i have the latter ones growing in a pot. planting instruction should come with them https://www.almanac.com/plant/cannas

canna lilies rarely start readily from seed. you are better off dividing the rhizomes.

We should

The seeds need to be scored...i.e. Open the outer shell of the seed with a small cut or use a file. HTTPS://www.gardeningknowhow.com/

the growth rate from seeds is about 2percent will grow. You have to make a cut in the outer layer of the seed, then soak to soften, and plant.

one more time....my posts keep disappearing again. You will need to cut the hard outer layer of the seed, then soak in water, then plant. Less tha 2 percent of the seeds will grow.

you will have to score them to open the outer layer of the seed , then soak them, then plant.
