Bitterweed's yellow blossom is a typical aster with a cluster of disk flowers and separate ray flowers. H. amarum typically has five to ten ray flowers hanging down from the dome-shaped disk.

This is var. amarum, which is the more widespread of the two Helenium amarum varieties. The other variety, var badium has a brown central disk, and is found only in Oklahoma, Texas, and South Carolina.
