Golden Alexander (Zizia aurea)

Golden Alexander (Zizia aurea)

Golden Alexander is the spring prairie's first golden wildflower — its flat-topped clusters of bright yellow flowers appearing in April and May when the native bee world is just waking up and desperately needs nectar. It is a member of the carrot family, and like all members of that family, its open, accessible flowers welcome an extraordinary diversity of small native bees, wasps, beetles, and flies that larger, more complex flowers exclude.

Ecological Role

Golden Alexander is a host plant for the Black Swallowtail butterfly and the Ozark Swallowtail — its leaves the food source for their caterpillars, which mimic bird droppings in early instars and sport the classic green-and-black swallowtail pattern in later instars. Its early spring bloom makes it one of the most critical nectar sources for native bees emerging from winter dormancy, including specialist Andrena bees. It is one of the few native wildflowers that thrives in both sun and part shade, making it exceptionally versatile in the garden.
