Pasture Weed Spotlight:
Prickly Sida and Arrowleaf Sida
Prickly sida (Sida spinosa L.) and arrowleaf sida (Sida rhombifolia L.) are common perennial weeds, especially in row crop fields in the south. They can also find their way into pastures, especially where grass stands are thin or where the pastures are overgrazed. Both are erect and can grow to 3 feet in height. The plants look similar; however, the leaves of the arrowleaf sida are more diamond shaped than those of the prickly sida and are only serrated along the tip half of the leaf margin. Both plants have small spine-like projections at the base of their leaves, and both have small, yellow flowers
