Golden Alexanders
(Zizia aurea)

Golden Alexanders (Zizia aurea) is a native perennial herbaceous plant belonging to the carrot family (Apiaceae), commonly found across eastern and central North America. It typically grows between 1 to 3 feet tall, forming clumps with upright, branching stems. The compound leaves are bright green with serrated edges, and the lower leaves are often divided into multiple leaflets. From late spring to early summer (May to June), Golden Alexanders produce flat-topped clusters (umbels) of small, vibrant yellow flowers, each less than 0.3 centimeters long, creating a striking visual display in meadows, prairies, and open woodlands. ​
This species thrives in full sun to partial shade and prefers moist, well-drained soils, commonly inhabiting moist prairies, thickets, open woods, and along streams. It is adaptable to various soil types, including clay, loam, and sandy soils, and is hardy in USDA Zones 3 through 8. Golden Alexanders are tolerant of seasonal flooding and can withstand dry conditions during summer, making them suitable for rain gardens, pollinator gardens, and naturalized areas.
Ecologically, Zizia aurea plays a significant role in supporting pollinators. It serves as a host plant for the caterpillars of the Black Swallowtail (Papilio polyxenes) and Ozark Swallowtail (Papilio joanae) butterflies. Additionally, its flowers attract a variety of insects, including bees, wasps, and other beneficial pollinators, by providing accessible nectar and pollen. ​
