nonbusbus believes this and comments on my article about growing arrow roots:
“Queensland Arrowroot, Cannus Edulis, is a better arrow root (in my opinion, but you can't agree, lols) to grow. It's an EXCELLENT addition to malodorous swamp water, lols – I know you like Leucaena, but it's a terribly invasive way that I live and our home landscapes are weed enough. Comfrey simply does NOT grow where I live – much too hot and humid, it is a pathetic breeder and I can only grow it as a yearbook in autumn / winter. However, Qld Arrowroot grows all year round, the yound tubers are YUM, I can get starch for my cooking from older tubers (less reliant on thickener supplies), it produces hard enough to grind regularly and for mulch or compost too fall dump, can be divided regularly, leaves are nourishing for animal feed and it works like comfrey when added to compost and weed teas – does a good job even with a good potassium level. Also creates amazing shadows. If you want to add arrowroot in your garden, definitely grow Cannus Edulis !! "
I have used the ornamental cannas in my food forest both as a chop and as an edible root, although I have not grown a variety that was bred specifically for good roots.
About a month ago, I planted a semi-wild canna strain in my vegetable gardens to chop and drop. I dug it from a friend's garden after asking if I could have any.
"It's a weed!" he said. "You want to take my weed?"
Sure, if it's good for compost production! I love these chop and drop plants. I also believe in growing everything that works best in your climate and what you like to eat. Depending on the climate and palate, there are often many solutions to the same problem.
Thanks for the comment, nonbusbus. I think I have to plant more cannas.
