About plant names...
Rough-stemmed goldenrods are natives of North America. For a comparison chart of some of the varieties of goldenrods, see
Solidago .
Identification: Plants are up to 5′ (1.5 m) tall.
Rough-stemmed goldenrods are named for their
hairy, rough stems , which are light green to brownish red. Plants lack the [Glossary("rosette" of leaves)] that are at the base of many goldenrods.
Leaves are narrow closer to the base of the plant, widening and becoming more oval-shaped toward the top, and
usually quite wrinkled in appearance (the species name, rugosa, means "having a rough, wrinkled surface).
They are up to 2½″ (7 cm) × ¾″ (2 cm), and attach directly to the stem ("sessile "). Flowers are a pyramid-shaped group of panicles at
the top of the plant, with multiple flowering branches of upward-pointing flowers . (Younger plants may have
only a single spike.) Flowers are bright
yellow, about ¼″ (6.3 mm) around, with a small yellow disk surrounded by 5-10 rays. Flowers appear
from July to October.
Edibility: Not edible.
Medical: Although goldenrod is popularly blamed by many
hay fever sufferers, the real culprit is ragweed .
