Solidago rugosa Mill.
Wrinkleleaf Goldenrod, Wrinkle-leaf Goldenrod, Rough-leaved Goldenrod, Roughleaf Goldenrod, Rough-stemmed Goldenrod, Roughstem Goldenrod
Asteraceae (Aster Family)
USDA Symbol: soru2
USDA Native Status: L48 (N), CAN (N), SPM (N)
Thin sprays of arching flowering stems occur at the top of sturdy, erect, 2-6 ft. stems. The numerous, narrow, toothed leaves are rough-surfaced.Tall, rough, hairy stem bears divergent, or arching, branches with small, light yellow flower heads concentrated on the upper side. The plant occurs in clumps.
This highly variable goldenrod can form large masses in fields that were once cultivated. Physicians in ancient times believed that goldenrod had healing powers; in recent times these plants have been popularly blamed for causing hay fever, but the irritating symptoms often attributed to it, are actually caused by ragweed (Ambrosia spp.), which produces the afflicting pollen in abundance when goldenrod is in flower.

PropagationDescription: If seeds are sown fresh, plant outdoors. Germination is often poor so sow thickly. Stem tip cuttings can be taken in May or June. Division of the basal rosettes, usually in late winter, offers the easiest method of increase. Mature plants can yield 30
Seed Collection: In October, examine a tuft of nutlets. If they are off-white or gray, they need more time. Mature seeds are white. Most seeds are flat and not viable. Viable seeds are thicker. Seeds remain in the heads for several weeks past the first frost. Store dry in sealed, refrigerated containers.
Commercially Avail: yes
