Solidago puberula, the downy goldenrod,[4] is a plant species native to eastern North America from Nova Scotia and Ontario south to Florida and Louisiana. Two subspecies are commonly recognized:[2][5]

  • Solidago puberula subsp. puberula
  • Solidago puberula subsp. pulverulenta

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 long.[6][7][8][9]
