Well, the bamboo stakes that I could find seemed expensive to me, at about 6 for 3.98 or so. And I would need dozens if not hundreds. So for the time being I am just cutting branches and tying with twine. I would like to find something better but for now the iris bed looks a lot better. I know there are shorted ones that don't need staking, but the tall ones I have usually succumb. Where is the info about varieties that don't need staking?
