- Description
-
Groundsel is a native shrub in the aster family (Asteraceae) found in mostly coastal areas of the eastern US, Canada and Mexico. It is commonly found in salt marshes, sandy locations, wet disturbed sites, near a road or in fields. The genus Baccharis is named after the god of wine and the species epithet is for leaves with resinous grayish-green leaves.
This plant is commonly seen as a multi-trunked plant with an irregular, open, airy habit that can become leggy. It will grow 5 to 12 feet tall with a 4 to 7-foot spread.As a seedling it resembles lambsquarters. Plant in full sun to partial shade in a range of soil types including infertile and wet sites. It is heat, drought and salt watert. It can be an aggressive spreader and is considered weedy, especially in agricultural areas.
Plants are covered with white to cream-colored flower heads in fall and winter. The showy seedheads that follow are frilly, white and dispersed by the wind on female plants. Groundsel is dioecious meaning a male and female plant is needed for fruit set.
Hand weeding is the best way to control the spread of seedlings. Herbicides are not very effective.
This shrub can be used in rain gardens, bog gardens, along ditches, ponds and streams or in naturalized areas.
Insects, Diseases, and Other Plant Problems: No significant problems. Weak wood is easily broken. Toxic to cattle if eaten in large quantities.

Fruit:
- Fruit Color:
- White
- Display/Harvest Time:
- Fall
- Fruit Type:
- Achene
- Fruit Description:
- The female plant is covered with cottony plume-like, pyramid-shaped achene that persists into early winter and is dispersed by wind. They resemble silver paintbrushes and are called pappi. Displays from September to November. Seeds are shed in late fall or winter, but the seeds of the female plant (this plant is dioecious) are poisonous. Wind dispersed seeds blow into landscapes during the winter months, making this a weedy plant.
