Tall Goldenrod (Solidago altissima) vs. Giant Goldenrod (Solidago gigantea)
Updated February 4th, 2025These two tall, thicket-forming goldenrods have a large range overlap and are easily confused. Both have triple-veined leaves and similar inflorescences. They are usually easily told apart by texture of the stems and leaves, and they have many other differences. Although their habitats overlap slightly, Solidago gigantea ranges farther north, is more restricted to richer, moister habitats, and is more tolerant of shade and poor drainage. Solidago altissima is more of a generalist, ranges farther south and into drier habitats, but requiring better drainage.
