Comprehensive Description

Read full entry


This native perennial plant is 3-4' tall and unbranched, except for the upper flowering stems. The stems are covered with white hairs. The opposite leaves are up to 5" long and 1" across, occasionally with small teeth along the margins. They are usually dark green, lanceolate to narrowly ovate, and pubescent. There are three conspicuous veins that run along the length of each leaf. The rather flat inflorescence consists of numerous heads of small white flowers and their buds. These flowers are dull white and individually only 1/8" across. There is little or no floral scent. The blooming period occurs from late summer to early fall, and lasts about 1-1½ months. The achenes develop small tufts of white or light brown hair; they are dispersed by the wind. This plant may spread vegetatively through rhizomes. Cultivation
