Lamb's quarters Chenopodium album* is a very common North American weed, and a close relative of spinach and quinoa. It is prized by the foraging community as an abundant and nutrient-dense green, found in suburban yards as well as urban sidewalk cracks.

The shape of the leaf and the tiny white-green flowers help identify it, but those red dots are the dead giveaway. Those are left by the nymphs of the Chenopodium leafhopper Norvellina chenopodii,** a small attractive insect that pierces the leaf with a tiny beak, sucking the juices of lamb's quarters.

* Chenopodium album literally means "little white goose foot."

** I couldn't find any reason for the name "Norvellina." It was probably named in honor of someone named Norvell. "Chenopodii" refers to the insect's host plant.

Urban species #135: Lambsquarters Chenopodium album

When wild foods enthusiasts talk about the superior nutrition of wild collected plants, lambsquarters is the best example (though dandelion is no slouch). Also called wild spinach, this sidewalk weed is very similar to Popeye's favorite green in nutritional content, and superior in some categories. Pictured above is the spring rosette, when the plant should be harvested, before it becomes too bitter. As summer comes, this weed will grow to four, five, or even six feet, and will bear small, green, inconspicuous flowers.

The strange common name, and the Genus name (Chenopodium means "goose foot") come from the shape of the leaves. A butcher's cut of lamb, and the foot of a goose are apparently similar in silhouette. Another common name used for this plant is pigweed--but other weeds share that name, making it less useful than others. The literal translation of its scientific name is also used: white goosefoot. Lambsquarters is native to Eurasia, and its seed is thought to have been accidentally introduced to North America in livestock feed.
