Description

The petioles are often over an inch long attaching the hairy stem to the hairy leaves which are usually divided into three leaflets.

The yellow, five petaled, flower has five reflexed sepals. Each petal is usually less than a third of an inch long.

The achene fruits grow in clusters of up to 35.

Native to the Canary Islands, North Africa, and Europe it thrives in disturbed areas, particularly in moist ones.

Often considered a weed, this broadleaf, winter annual germinates in the fall or winter and remains dormant until spring.  However warm weather in winter may trigger growth. It matures and produce seed in the spring dieing in late spring or early summer. It can quickly out compete weak turf particularly where the soil is moist or in shade.

Healthy turf is the best way to prevent winter annual weeds. Select  a variety adapted to your area and fertilize, mow and water at recommended rates.The low, broad growth habit is not hampered by mowing. Consider these weed management strategies
