I live in Massachusetts, Zone 6. Last July I bought a beautiful Gaillardia Arizona Sun. It bloomed all summer and into the fall. According to what I was told, as well as my online research, it's a perennial, however, there's no evidence of it so far this year.
Most of my perennials, including hostas, lilies, iris, dianthus, peonies, and others, are showing foliage. Some are even budding or blooming. Is it too soon to expect to see at least something emerging, or should I assume the Gaillardia died over the winter?
