Solidago ouachitensis is a North American species of flowering plants in the family Asteraceae known by the common name Ouachita Mountain goldenrod. [2] It has a very limited range, found only in the Ouachita Mountains along the border between Arkansas and Oklahoma in the United States. [1] [3] [4] [5]
Solidago ouachitensis is a perennial herb growing up to about 1.1 meters (44 inches) in height. It produces one or more erect stems from a woody caudex. The serrated (toothed) leaves are 10 to 13 centimeters (4.0-5.2 inches) long around the middle of the plant and smaller higher on the stem. One plant will produce 25-50 bell-shaped flower heads. Each flower head usually contains one yellow ray floret and 4-5 disc florets. [6] Flowering occurs in September and October. [3]
Solidago ouachitensis is likely a relict of times when conditions were colder and wetter. It only occurs in the cooler, moister sites in the Ouachita Mountains, [3] usually in wet forest habitat on north-facing slopes. [1] Associated species include Magnolia tripetala , Fagus grandifolia , Acer rubrum , Quercus rubra , Aesculus glabra , Asarum canadense , Campanula americana , Panax quinquefolius , Toxicodendron radicans , and Hybanthus concolor .
