A very obnoxious noxious weed is called puncture vine. Roger Batt says “puncture vine is easy to kill but the problem is that its seeds can last in the soil for 50 years and still be viable. You can see by looking at it why they call it a goat head. It does look like a goat’s head. Very sharp. You may have stepped on one of these in your carpet if you have been out in it. It’s very painful. It punctures bicycle tires or any other tire that has air in it.” Puncturevine or goathead is a prostrate, summer annual, mat-forming, broadleaf plant with an extensive root system. Listed as a “C-rated*” noxious weed in California, puncturevine produces many burs with sharp spines that can injure humans and animals, as well puncture bicycle tires. $25-$30 million is spent collectively each year to battle these unwanted noxious invasive weeds.
