Golden Alexander: How to Care for Zizia Aurea

Golden Alexander: How to Care for Zizia Aurea
Golden Alexander (Zizia aurea) is a native North American perennial wildflower known for its yellow, firework-like blooms that bloom in mid-spring—and, more importantly, for being the host plant for the black swallowtail butterfly.

The plant has a long bloom time, about a month.
Golden Alexander is part of the carrot family and looks very much like wild parsnip, which contains sap that is phototoxic (skin contact with the sap, followed by exposure to sunlight, can cause a rash).

Three ways to tell the difference between the golden Alexander and wild parsnip are size, leaf shape, and bloom time.
