Autumn helenium is covered with bright golden daisy-like blooms on 4-foot plants late in the growing season. It prefers moist soil and is good in low spots or rain gardens. Autumn helenium is one of the host plants of the Dainty Sulphur. The genus is thought to have been named by Linnaeus for Helen of Troy (the legend is that the flowers sprung up from the ground where her tears fell).
