Update: The dry creek bed is completed. It will take some time before the rain lilies get established and begin to bloom when it rains. I'm sure the wild violets will find their way to line the edges. I plan to order some Louisiana Iris when I can make up my mind which color to order. They only ship in the fall so it will be some time before my plain dry creek bed gets decorated properly. We have had several heavy rains and the water is being diverted very well. My husband has finally succeeded in getting grass to grow now that his seed doesn't get washed away anymore.
