Broadleaf Weed – Sheep Sorrel

(Rumex acetosella)

Sheep Sorrel – also commonly referred to as Red Sorrel, Sour-grass, Indian Cane, Field Sorrel, Horse Sorrel, Cow Sorrel and Red-weed – is a perennial broadleaf weed. Rumex acetosella prefers acidic soils and is commonly found in fields, glades, waste areas, and in gravel along buildings, along driveways, roadsides and railroads. Sheep Sorrel can be found in nearly every state and province in North America.

Identifying Sheep Sorrel -

Sheep Sorrel is a rhizomatous perennial with primarily basal leaves and stem leaves that are fewer and alternate. Its leaves are thick, petiolated, smooth and dull-green in color. A papery or membranous sheath surrounds the stem just above the point of leaf attachment. Sheep Sorrel has a yellow taproot and numerous slender rhizomes.

Blooming from May through September, Sheep Sorrel features slender, vertically flowering stems that are four-sided and typically maroon to red in color. Each flower consists of six sepals without petals. Because it is a dioecious weed species, Sheep Sorrel produces exclusively male or female plants. The flowers on male plants have six stamens and transition from green to reddish-brown in color. The flowers on female plants are red to yellowish-brown in color.

Sheep Sorrel Control -

Sheep Sorrel is rather difficult to remove with cultural weed control methods alone. Physical removal (or “weed pulling”) is not recommended as rhizome segments are often left in the soil, sprouting new plants.
