Description

Solidago speciosa is indeed one of the showiest goldenrods. The unbranched, rigid stems are reddish, up to 4' tall, the upper third of which will bear dense, yellow flower clusters. These are erect unlike the arching form typically associated with goldenrods. The leaves are alternate, lance-shaped, up to 6" long at the base of the plant, and gradually become smaller as they move up the stem.

Cultivation

Showy goldenrod is very easy to grow under typical garden conditions. It is tolerant of poor soil, and will thrive in slightly moist to slightly dry environments in full to part-sun. Overly moist, or fertile soil can lead to taller, weaker plants that will have a tendency to topple over without additional support. The root system is fibrous and rhizomatous, however, the plants do not tend to spread vegetatively. This species can provide intense color contrast in the late summer garden, or perennial border. It is also a favorite to naturalize wild gardens, prairies, and meadows. The blooming period lasts about a month, during late summer or early fall. Zones 3-8

Propagation

Propagate by division in spring. Though seed germination rates can be improved through cold stratification, this is not a requirement.

Additional Notes

Solidago speciosa is an excellent late season source of nectar and pollen for a variety of native bees and butterflies.
