Some residents from the Foothills in Yuma Arizona contacted the Vegetable IPM for identification of the following weed invading their yards. This weed is called Skeleton Weed or Flat Crown Buckwheat: Eriogonum deflexum from the polygonaceae family.
Leaves: Round to kidney shaped.
Flowers: White with a branched inflorescence.
Common in the Sonoran desert and Mexico in young stages may look very different than mature plants and therefore its identification can become difficult.
