Perennial Pepperweed

Lepidium latifolium

As the name implies, this plant is a perennial and grows from 1 to 4 feet tall.

Reproduction is by creeping rhizomes and by seed.

Leaves are lanceolate, toothed or entire, with basal leaves larger than upper leaves.

Flowers are snow white and clustered in dense racemes near the ends of the branches.

Also called “giant whitetop”.

This plant has the ability to grow in very alkaline, boggy areas. Dense stands ruin waterfowl nesting habitat and crowd out desirable native vegetation. Perennial pepperweed is found throughout the county along riparian areas.

CHEMICAL CONTROL:

Chemical choices are limited for the control or perennial pepperweed. Contact your local weed and pest for recommendations.
