 General Description:

Puncturevine is an annual. Plants form mat with trailing stems 3 to 5 feet in length. Hairy leaves are opposite, oblong, and divided into four to eight pairs of leaflets. Flowers are small, yellow, 5-petaled, and are produced in axils of leaves. Fruits consist of five sharp, piercing spines. Burs separate as they mature and often lie in the soil for years before germinating.

Herbicide Control Notes:

  • Gramoxone cannot be used in actively growing mint.
