|discussion=<p><i>Solidago gigantea</i> is usually the least hairy species of the <i>S. canadensis</i> complex. The stems may be somewhat glaucous and the array is usually somewhat more open than in <i>S. canadensis</i> and <i>S. altissima</i>, and less leafy than <i>S. lepida</i>. Its blooming season begins and ends earlier than <i>S. altissima</i> in eastern North America. The species is diploid, mostly east of the Appalachian Mountains, tetraploid throughout the eastern forest area, and hexaploid on the prairies. The broader-leaved hexaploids on the prairies have been treated as S. shinnersii; G. H. Morton (1984) indicated that the differences are not diagnostic. Reports of hexaploids in the mountains from Alberta, Idaho, Oregon, Washington, and northwestern Wyoming all have minute stipitate glands on the phyllaries, peduncle bracts, and sometimes the distalmost leaves; such plants belong in <i>S. lepida</i>, as do plants from British Columbia. Stems sometimes have 1–2 elongate insect galls near the base (S. Heard, pers. comm.). Although reported from much of Florida, specimens were seen only from Liberty County; all other collections are <i>S. leavenworthii</i>.</p>
