Subsp. pulverulenta has smaller but more numerous leaves, generally 50-110 leaves {{convert|10|-|40|mm|in|abbr=on}} long halfway up the stem, as opposed to 10-60 leaves {{convert|40|-|50|mm|in|abbr=on}} long for subsp. puberula. Solidago puberula is a perennial herb up to {{convert|100|cm|in|round=0.5|abbr=on}} tall, with a branched woody rootstock. It can have 1-5 puberulent (hairy) stems. Leaves are toothed, tapering at the tip, puberulent on both sides. Flowering heads number 15-250, in an elongate, paniculiform array. Ray flowers are yellow, 9-16 per head. Disc flowers number 6-15 per head, each up to 3 mm long.[6][7][8][9]References1. ^USDA-NRCS PLANTS Database / Britton, N.L., and A. Brown. 1913. Illustrated flora of the northern states and Canada.
