FAMILY: Compositae (Asteraceae)
HABIT: Perennial herb to 1.7 m.; flowering
August-October; fruiting September, October.
SPECIES: Solidago is an extremely
complex genus with many species in Ohio.
S. squarrosa is distinguished from other similar species by a
combination of leaf and flower characters.
Non-flowering material cannot be identified with certainty.
RANGE: N.B. to s. Ont., s. to OH, s.
IN, and in s. uplands to NC.
RANGE: There are post-1960 collections
from Ashtabula, Athens, Cuyahoga, Geauga, Holmes, and Vinton Counties, as well
as a Washington County specimen with vague locational information. There are pre-1960 records from 11 counties:
Ashland, Erie, Highland, Hocking, Jackson, Lake, Licking, Lorain, Ross, Scioto,
STATUS: 1980-1995: Threatened,
1996-1999: Potentially Threatened, 2000 to present: Threatened.
HABITAT: Rocky upland woods, thickets, and clearings.
HAZARDS: Unknown, perhaps overshading by woody
species as a result of succession.
POTENTIAL: Unknown. However, this species may respond favorably
to thinning of forest canopies or planting in its native habitat.
GUIDELINES: Examination of the complete
plant, including underground parts, basal leaves, and mature flowering or
fruiting material, is necessary for positive identification of species of the
COMMENTS: This is a fairly distinct, showy-flowered
plant that is unlikely to be overlooked or misidentified. Its relatively numerous historical records
suggest that it was once widely scattered throughout eastern Ohio, but is now,
for the most part, restricted to the southern part of the state. It should be sought throughout eastern and
