I have a question about canna lilies. I live in Augusta, Ga just so people may know climate. Yesterday morning I did my watering to my lawn and flower beds; everything looked fine. Yesterday afternoon the sky got really dark and the wind was heavy for a moment before I left out. This morning when I walked out, the leaves have a yellow/white look to them and a lot of the plant is dropping over on the ground. It looks as something rolled over them. I planted them in June and they seemed to be thriving and overnight look as if they are dead. Has anyone experienced this or have these at their home. Any info would be appreciated. Thanks all!
