Solidago leavenworthii
Solidago leiocarpa
Solidago leavenworthii replaces S. gigantea on the southern, outer Atlantic coastal plain and into Florida. The leaves of S. leavenworthii usually have fewer, smaller serrations than those of S. gigantea, and they have a distinctive dark, somewhat olive green color. The pyramidal array of S. leavenworthii is usually much narrower and elongate while that of S. gigantea is usually broad and not elongate.

Solidago leiocarpa is similar to and possibly conspecific with S. multiradiata. It has long been treated as S. cutleri in regional floras.
