About plant names...

Giant goldenrod is a North American native. For a comparison chart of some of the varieties of goldenrods, see Solidago.

Identification: Plants are 3-7' (91-213 cm) tall, erect. They are fond of boundaries of wetlands and shaded floodplains. Stems are light green or pale purple, hairless, sometimes with a whitish waxy bloom. They occur in large patches. Leaves are narrow (lanceolate), ~3½" (9.1-9.7 cm) × ⅜-½" (1-1.4 cm) (roughly equal in size throughout the plant). They are pointed at both ends, alternate, sessile, with sharp teeth and three veins. Flowerheads may be tight and roughly conical, but are often looser, composed of gently curved tiers of up to 600 small yellow flowers.
