Cut-Leaved Evening Primrose
Oenothera laciniata
Onagraceae (Evening Primrose) Family

Cut-Leaf Primrose is also known as Evening Primrose and Garden Primrose, Weedy Evening Primrose and Sundrops.

Plant is an upright or sprawling woody biennial weed. New stem growth arises from the axil formed by older leaf and stem. Preferred habitat is roadsides, waste areas, old fields and gardens. Distribution is throughout the Escambia region.

Leaves are thick; hairy; widest at the middle; alternate on the stem; deeply cut or saw-toothed; more or less smooth above; silvery green; sunken mid-vein is prominent beneath. Short and stout leaf stalks may appear to be clasping the stem.

Flowers arise from the leaf axil; yellow, fading to pink or orange with age; four petals; numerous stamens. Flowers occur in late spring and summer.

Fruit is an elongated capsule.

The closely related Seaside Evening Primrose (O. humifusa), has leaves that are entire (no teeth and no lobes) and about one inch long; even more woody than the Cut-Leaved Primrose. Seaside Primrose is found strictly in coastal areas, back-wash and dunes.
