Here are photos of Pitseed Goosefoot (Chenopodium berlandieri) growing in my apartment laboratory. The green plant is my local native variety from here in Southern California. The red stemmed plant is a cross I made of my local with the ancient cultivar from Mexico known as Huauzontle or Aztec Spinach. Pitseed Goosefoot is widespread across North America and into South America, and is believed to be the ancestor of Quinoa. The plant seems to be getting rare in my area. I see far more introduced weedy foreign Chenopodium species.
