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?
I'm interested to know more. What has your experience been so far? Have you had a chance to harvest them and try them out? There is a boggy spot on the property we are buying and I'm looking for water-loving plants to try out. I was initially under the impression that this was the same plant used to make arrowroot powder, but now I know differently. Here's what I learned from my research:
-They are from the diverse order Zingiberales
-There are over 100 species of the genus Canna -The plant from which arrowroot powder is made is in a different genus: Maranta arundinacea -The starch from C. edulis (Queensland Arrowroot) is very easy to digest.
-The rhizome clump of C. edulis can be two feet long!
Mine did not get large enough this first year to harvest from, as I didn't want to compromise their ability to survive our winter (which is usually mild). I expect to be able to harvest next year. I need to put some in a more improved bed for faster growth; they're currently in an edge part of the garden which doesn't get a lot of water or soil improvement.
do you remember why it is not grown from seed? In the mountains it does not grow like a weed but it grows and dies down in winter. I think I remember that you have to eat the small corns, probably they are not really good otherwise no one would have made flour out of them.
