Practical Weed Science for the Field Scout: Corn and Soybean

Eveningprimrose, cutleaf (Oenothera laciniata)

Winter annual broadleaf

Eveningprimrose, cutleaf
Eveningprimrose, cutleafCutleaf evening-primrose is almost always a biennial or a winter annual unlike common eveningprimrose which is more often a summer annual. Cutleaf eveningprimrose has leaves with deeply toothed margins and produces many showy yellow or red flowers. Leaves initially develop as a basal rosette. Young leaves have margins that are untoothed, but subsequent leaves have toothed margins. Mature plants have leaves that are lanceolate in outline, are relatively narrow with a white midvein, and have deeply toothed margins. The fruit is a capsule that is about 3/4 to 1-1/2 inches long and often curved.
