Golden Alexanders (Zizia aurea) is a seasonal plant with yellow flowers late spring into early summer. They prefer moist to mesic soil in sun to part sun where they grow up to 3 feet tall. They are a good choice for banks and slopes. Companion plants include Purple Coneflower (Echinacea purpurea) and Little Bluestem (Schizachyrium scoparium).
