Heart-Leaf Golden Alexander vs Golden Alexanders
These two species are sometimes confused where their ranges overlap. They are usually easily distinguished by examining the basal leaves. Although they have some overlap, Zizia aptera is usually found in drier habitats. Often the trickier ID challenges are comparing either of these to similar-looking species in other genera.
