I'm starting some Queensland Arrowroot, Canna edulis, from seed in my aquaponics tank. I poured nearly-boiling water over the extremely hard seeds, soaked them overnight, and put them in a small pot of soil, set in shallow water. They've sprouted very well and are looking good.
I've eaten a mystery cultivar of Canna and it was kind of yucky, so I hope these are better. Taste is supposed to be bland. Bland I'm ok with, I'm very happy to avoid yucky!
Anyone else here growing and eating Queensland Arrowroot?
