Growing conditions: Plants should be placed 1 foot apart. This is an excellent low-growing perennial for heavy clay soils in semi-shade to full sun.

Environmental benefits: It is a host plant for the caterpillars of the black swallowtail and Ozark swallowtail. Females of the mining bee species Andrena ziziae eat only its pollen. Dozens of species of bees, flies, wasps, butterflies, and other insects visit the flowers of Zizia aurea for its nectar. Many short tongue pollinators and smaller butterflies use Golden Zizia as a nectar source. As a long-spring flowering plant, it provides nectar when few flowers are blooming. It is deer resistant.
