Perennial Canna (Canna edulis) is an abundant permaculture plant in the subtropics, also known as Queensland Arrowroot. I can't imagine how I would have got my garden to this stage without it's help.
It is an amazingly useful plant that I have used it extensively in the establishment phase of my garden to:
- create a super fast growing in-garden windbreak;
- create a super fast growing in-garden sun shade for sensitive plants in summer;
- develop a vegetative terrace to stop soil, water and mulch slipping down the slope;
- establish a weed barrier along with comfrey and lemongrass around new garden areas;
- make a living fence. I plant Canna beside a little chickenwire fence . I find the wild animals and chooks are less likely to jump/fly over the fence if they cannot see what is on the other side;
- produce abundant organic matter for the garden;

Amazing growth in one season. You can keep chopping it too throughout the growing season and it will continue to grow back. What a gift! - grow plentiful chop and drop mulch;
- cut as food for the chickens;
- grow materials to bulk out the compost piles;
- provide habitat for frogs.
There are of course many delicious ways to eat it too, but I'll leave that for another post.

I grow Canna edulis because it I like the fact that it is edible too - it really is so productive and abundant, with virtually no pests or diseases and can grow in just about any conditions (as long as it's warm). Here where I get some frosts, it dies back over winter, but returns with the warm weather .




Thanks for that. I knew the flowering type were a bit of a problem.
ReplyDeleteI was going to pull mine out until I realised the silkies were seeking shelter and shade under them.
ReplyDeleteOur arrowroot got frosted but will grow back soon. They certainly are fast growing.
