Comprehensive Description

Read full entry


This native perennial plant is 3-5' tall, branching occasionally and becoming rather bushy in open situations. The light green stems have scattered white hairs and are rather angular. The opposite leaves are up to 5" long and 3½" across, ovate to broadly ovate in shape, and coarsely serrated along the margins. They are usually dark green and have a rough texture. The daisy-like composite flowers are 2-3½" across. They are usually held erect and occur individually at the ends of flowering stems. The ray florets are light to golden yellow, while central disk florets are a slightly darker shade of yellow and form a flattened cone. Both the ray and disk florets are fertile, and can form viable seeds. There are no tufts of hair attached to the seeds. The blooming period occurs from early to late summer and lasts about 2½ months. There is no noticeable scent to the flowers. The root system is fibrous.
