DESCRIPTION: This annual grows one to two feet tall with spines on stems, leaves, and seed heads. Leaves are heavily lobed and have prominent veins. Yellow, five-lobed flowers adorn buffalobur throughout the summer.
CONTROL: Biocontrol is not available. Herbicides can offer excellent control. Diligent digging of this weed can offer good control. Contact your local state or county weed specialist for specific updated information.
