Zizia aptera is an herbaceous perennial plant that is part of the carrot family, Apiaceae. The central flower lacks a flower stalk, distinguishing it from other members of the group. This plant is characterized by its yellow flower clusters (known as umbels) that bloom in the late spring and early summer. Each umbel can have up to 1-15 umbellets (flowers on the umbel). The leaves of the plant have a characteristic heart shape. Common names for the plant include Heartleaf Golden-Alexander and Heart-leaved Meadow Parsnip.

Zizia aptera is a popular plant in pollinator and rain gardens.

Wildlife value: A variety of pollinators (including bees, butterflies, beetles, and pollinating flies) feed on the nectar and/or pollen of the flowers. Zizia aptera is the host plant for the larvae (caterpillars) of Black Swallowtail butterflies.
