Biology

Shepherd’s-purse is an annual or winter annual (sometimes a biennial) plant with a thin taproot. The leaves are primarily in a basal rosette and may have smooth edges or be variously lobed or toothed. The leaves are somewhat hairy beneath. Flowers are borne on long upright stems rising from the rosette of leaves. Typically, some smaller leaves occur along the flower stalks, sometimes with branches in the leaf axils. The small, four-petalled, white flowers occur singly and begin blooming at the lower part of the stem first. Seed pods develop on 1/2-inch stalks and are heart-shaped to triangular. It is common for nearly mature seed pods and unopened flower buds to be present on the same stem (at the bottom and top of the stem, respectively).

Habitat

Shepherd’s-purse is a weed of gardens, fields, waste areas, and similar cultivated or disturbed sites.

Management Options

Use Integrated Pest Management (IPM) for successful plant problem management.

Non-chemical Management

Select non-chemical management options as your first choice!

  • Maintaining a healthy planting or turf area to provide competition will prevent weed establishment.
  • Cultivation (rototilling or hoeing) will effectively eliminate plants.
  • Reduce weed infestation by handpulling weeds.
