Thanks again Norma Rosa!
I have found this plant to be a "mexican pricklypoppy" (Argemone Mexicana L.)
Medicinal use: sedative
Disclosure

This species is considered a noxious weed in the U.S. a catagory 5.
The Noxious Weeds Act of 1993 declares and classifies plants which are a danger to human health, serious economic pests, and invaders of natural systems.
I love the DR!!
