Puncturevine (Tribulus terrestris) on Aug 10, 2019

Submitter has sample
EDRR Status: Local expert notified

Description of specimen

It is a small weed that spreads along the ground. It has green leaves and small flowers, but it also has sharp balls with spikes coming out of them. We got rid of it once with weed spray and pulling everything out, but it has returned. It was here last year, but I didn't identify it. It has punctured tires, hurt pet's paws, and hurt kids' feet.


Good afternoon Carly,

Thank you for taking the time to stop by our booth at the County Fair and for reporting your observation of puncturevine near your home.

We greatly appreciate your report. Puncturevine is a priority weed in Clackamas County and we are working hard to try and limited its abundance and spread.

WeedWise program specialist, Justin Cooley was out last week and confirmed your observation. Justin is currently planning a round of puncturevine treatments and will be contacting you soon to arrange treatment.

If you would like more information about puncturevine please review the following informational links.

Please feel free to contact me directly if you have any additional questions.
