Summary

Solidago gigantea, commonly known as Giant Goldenrod, is a deciduous perennial herb native to meadows, prairies, and along roadsides and streams throughout the Central and Eastern United States, as well as Northeast Mexico. It can reach heights of up to 2 meters (6.6 feet) tall and is known for its ability to spread via underground rhizomes, often forming dense clumps. The plant is characterized by its tall, erect stems with lanceolate leaves that become smaller as they ascend. The upper part of the stem culminates in a large, showy inflorescence composed of numerous small yellow flower heads, each containing both disc and ray florets, which bloom from late summer to early fall.

Giant Goldenrod is valued for its vibrant yellow flowers that attract pollinators and its adaptability to a range of soil conditions. It is often used in naturalistic plantings, wildflower meadows, and as a border plant in gardens. While it prefers full sun or part shade, it can thrive in soils with medium to slow drainage. However, gardeners should be aware of its potential to spread aggressively; it is highly invasive throughout Europe and Asia, displacing native species and requiring active management.CC BY-SA 4.0
