Flaxleaf Fleabane
Erigeron bonariensis (eh-RI-jeh-ron boh-nair-ee-EN-sis)
The common name, Hairy Fleabane is derived from the stiff bristles that are found on the stems, leaves and flowers of this plant. It has been thought that this plant, as well as other varieties of Erigeron could be used as a means of repelling fleas. That myth has proven to be incorrect, but the common names referring to fleas is still in use. Native to tropical America, this weed has spread to Europe, Africa, and Asia, as well as a few parts of the US. The plant is rarely found in North Carolina. It is a rapidly growing summer annual or biennial weed in the Asteraceae (daisy) family. It can be found in disturbed sides, roadsides, urban areas, and cultivated fields and even in the cracks in pavement. Considered weedy, it spreads when its fluffy seeds are blown by the wind, washed into the surrounding area by rainwater and by human activity. Seeds that are spread remain viable for up to 3 years. Elimination of this weed allows other more valued natives to survive, however, is curtailed by the plants' resistance to some herbicides. In commercial sites, such as orchards, its weedy nature has become problematic, interfering with the crops being grown. In South America, it is a host for the lettuce mosaic virus, affecting the yield produced. Flowers form in clusters that can bloom year-round. It is not recommended as an addition to any garden or natural setting. Insects, Diseases, and Other Plant Problems: This plant is considered to be invasive. Dermatitis can occur when contact with any part of the plant is made. More information on Erigeron .
