Help with weed identification

Asked October 20, 2017, 3:09 PM EDT

Good afternoon, We have found this weed popping up recently in our neighborhood, and no one seems to know what it is. We'd like to identify it, so we can figure out the best way to get rid of it. It's got some pretty nasty thorns hidden in it that are very painful to dogs! Photo is attached. Thanks in advance for any help!

The weed is called Sandmat (cardionema ramosissimum), it is a beach dwelling perennial plant in the pink family. Native plant of the West Coast.

Control options include:

Manual control: hoeing and digging, be sure to get the roots. Do it early in the summer before seeds are mature.

Flaming: works on small patches, but be careful not to use this if there is a chance of the fire escaping.

Mulching: adding a 3inch layer of wood chips in parks has helped.

Chemical control: most practical method in larger areas, or where other methods do not apply.

In areas where no vegetation is desired or where you are spot treating individual plants, you may use products with glyphosate (such as Round-up).

In lawns you may use products that contain Carfentrazone, 2,4-D, Mecoprop or Dicamba.

When using chemicals, always read and follow all label directions.
