Subsp. pulverulenta has smaller but more numerous leaves, generally 50–110 leaves 10–40 mm (0.39–1.57 in) long halfway up the stem, as opposed to 10-60 leaves 40–50 mm (1.6–2.0 in) long for subsp. puberula.
Solidago puberula is a perennial herb up to 100 cm (39.5 in) 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 (0.12 in) long.[4][5][6][7]
