Gaillardias don't seem to like my clay soil - duh
- Oranges and Lemons also did not come back for me. Neither did the box store standard red/orange. Did have an Amber Wheels overwinter and I just moved it to the only sandy soil spot in my entire yard. Seems to like it, has perked up and started shooting out a lot more buds. Was just given three Reveille so will try putting them in the same area and see. Sorry I don't have more extensive information for you, but I would be interested to know what other people have experienced and am glad you started the thread.
