It seems like it should work for you also Duane.
I amended my clay soil to about 2 feet, with forest compost. They didn't flower because the dog dug them up. I replanted and they made it through another winter, returned in the spring. Then I had my DD two dogs again. Izzy dug the two brugs up for the second year. They did not survive the last digging.
I dug out more lawn and put them in front of the poker lilies. Sorry I don't have a photo of them.
