Golden Alexander (Zizia aurea) is a perennial which occurs most often in small colonies in moist woods and meadows, thickets, glades and prairies. Features flat-topped clusters (compound umbels) of tiny yellow flowers in late spring atop stems growing to 3 feet tall. Distinguished from other carrot family members by the absence of a flower stalk on the central flower of each umbel. Both basal and stem leaves are compound biternate with toothed leaflets. The blooming period occurs from late spring to early summer, and lasts about 1 month. There is no floral scent. The seeds are oblong and flattened, but not winged, with several lighter-colored longitudinal ridges. The root system consists of a dense cluster of coarse fibrous roots.
Habitats include moist black soil prairies, openings in moist to mesic woodlands, areas along woodland paths, savannas, thickets, limestone glades, thinly wooded bluffs, powerline clearances in wooded areas, and abandoned fields. Golden Alexanders occurs in both degraded and higher quality habitats. It adapts readily to habitat restorations.
Grow in average, medium moisture, well-drained soils in full sun to part shade. The seeds can be difficult to germinate, otherwise this plant is easy to grow and maintain.
