Zizia aurea (L.) W.D.J. Koch
Golden Zizia, Golden Alexanders
Apiaceae (Carrot Family)
USDA Symbol: ziau
Golden alexanders is a short-lived perennial with branching, erect, reddish stems. The lower leaves are divided into threes twice while the upper leaves are divided once. The yellow flowers less than 1/8 inch long. Each tiny flower has 5 sepals, 5 petals, and 5 stamens. Separate clusters of tiny, yellow flowers gather into a large, flat-topped flower head, the middle flower of each umbel being stalkless. Dry seedheads turn purple, adding summer interest. The plant is 1-3 ft. tall.
Other yellow-flowering members of the carrot family include: Heart-leaved Meadow Parsnip (Z. aptera), with simple heart-shaped basal leaves; and Yellow Pimpernel (Taenidia integerrima), with compound leaves and untoothed leaflets. A common southern Meadow Parsnip of a different genus, Thaspium trifoliatum, sometimes called Golden Alexanders as well, has only 3 lanceolate, untoothed leaflets.
