Get Out and Pull Goatheads!
Goat heads, puncturevine, or devils thorn are all names for the same plant Tribulus terrestris. This is the plant that pops your bike tire, gets stuck in your dog’s paw, or stabs your foot walking through your yard. It is up to you to help eliminate it around Lassen County!
First: Go out into your yard or sidewalk and pull seedlings in early June (picture one). Check for new seedlings periodically throughout the summer.
Tip: Use old carpet pads to pick up last year's seeds. We will have carpet pad squares available for free on June 4-5 outside of the Historic Railroad Depot at 601 Richmond Road.
Learn More: Attend a Zoom Presentation at 7:00 pm on June 4th!

Biology: Reproduces only by seed, 3-6 years seed life. Multiple germinations per summer. Flowers 3-6 weeks after germination. Will not re-root from the stems.
Identification: Low growing plants forming dense mats with pinnately divided leaves and yellow flowers. Reddish stems grow out from central taproot. ID puncturevine as a seedling for easy control!
Habitat: Roadsides, sandy soils, walkways, mowed areas, etc.
Control: Tenacity and persistence are essential to eliminate seed production. Hand pulling, hoeing, and cultivation can work. Tall competitive grasses/forbs will outcompete puncturevine. Google “Puncturevine UC IPM” for information on chemical control.
