IDENTIFICATION

Puncturevine grows up to 10 inches or so and is a low-growing prostrate species.  Its stems range from silky to hairy and it has green compound leaves with 6 to 12 leaflets.  It also produces yellow flowers, breaking up into 5-nutlets with strong dorsal spines.

IMPACT

In North America, Tribulus terrestris is considered weedy or invasive by 46 states.

Tribulus terrestris is a weedy herb introduced from southern Europe and expanding its range throughout most of North America. Tribulus terrestris is aptly called "Puncture Vine" because its fruits easily puncture bicycle tires and ready inflict pain on unsuspecting humans and perhaps small mammals as well.

CHEMICAL CONTROL

Pre-emergent herbicides can help prevent puncturevine outbreaks if you apply before or during the growing season, which is March to October.
