The other day we tore ourselves away from our computers and headed out into the forest in the fading light to sneak in a brisk walk before bed. I have mushrooms on the brain, always, these days, so I was hoping to find some.

Our neighborhood at 10,000 feet on the mountainside at the base of a ski resort is crisscrossed with trails through the forest—some single-track, others wide enough for two to walk abreast—and most abutting gigantic micro-mansions that I think could make for stellar eco-villages come the apocalypse. But that’s beside the point.

We descended on a footpath first, then turned on a wider path across a bluff. The light was fading fast so I was eager to gain the road, but in that twilight, we were fortunate to come upon two frolicking fox pups. We watched them for a bit before I noticed the lambs’ quarters growing lush near some blue spruce trees, which must have been planted somewhat recently. The lambs’ quarters plants were happily escaping the property of the big house for which the spruces were planted to provide buffer.

Eat Me Please

Also known as goosefoot or wild spinach, lambs’ quarters (Chenodium album and related, similar Chenopodiums) are related to cultivated spinach and can be used similarly.

“Wild spinach is one of the most nutritious leafy greens ever analyzed, beating out domestic spinach in fiber, beta-carotene (vitamin A), vitamin C, riboflavin, calcium, zinc, copper, and manganese,” writes forager/author John Kallas, who has a Ph.D. in nutrition, in his 2010 book, Edible Wild Plants: Wild Foods from Dirt to Plate. He does point out, however, that domesticated spinach wins in omega-3s, folic acid, and iron.

Wild spinach has green to greenish-blue leaves that are covered, particularly on the underside and growing tips, with a white, mealy substance upon which water balls up and runs off. The leaves are shaped somewhat like a goose’s foot, hence the moniker. The flowers that come later are small, white-mealy balls clustered on the upper parts of the stems. The stems may have red striping along them.

This is a weed of garden beds and landscaping. Like a dedicated pup, it follows us humans around, much as we have sought it out. In The Forager’s Harvest (2006), Sam Thayer explains that the goosefoot C. berlandieri has been used by native people here for thousands of years, prior to contact with European settlers, who brought their own strain of edible Chenopodium to North American soils, whether or not intentionally. There is archaeological evidence for Chenopodium seeds in North America dating back thousands of years, he explains, citing Smith (1992). “Depending on classification, these seeds may or may not represent C. album; but some of them certainly represent plants that would commonly be called “lamb’s quarters,” he writes.

Lambs’ quarters are also related to quinoa, and the seeds can be used similarly after rubbing, winnowing, and soaking. I made sprouted flour from them once. If you are interested in that, see the January 2014 Wild Edible Notebook, in which I give a good go at processing seeds.

Landscapers, Let Me Live!

But this night what interested me were the fresh greens, the flower-heads included. I looked for signs of herbicide spray and did not see any, no tortured-growing or dead-deformed plants around. And it was 1/4 mile or so from the nearest road. I decided to gather a batch, stripping off leaves and young flowers from some of the plants.

Lambs’ quarters in this context does not naturally occur in the high elevation forest. It was likely transported here in soil, and is likely to be pulled entirely by landscapers, or worse, sprayed with killer toxins. It makes sense to make use of it, if assessed to be safe. So I made a judgment call and gave it a go.

I didn’t pull the plants out entirely, or collect from every one either, but I stripped some leaves and flower-heads, from about halfway up from a handful of individuals, spreading out my harvest in the hopes the patch will continue to flourish. I would like to see the plants thrive if they are not going to be landscaped out of existence. I like them, and there’s food enough for several nights. Fingers crossed.

I could eat wild pesto on bread for lunch every day.

Up here, in areas that are dry and open or too high up in elevation, lambs’ quarters grow to be pitiful little things, sometimes barely taller than my ankle. Such was the case at our old home at 11,000 feet in Fairplay. They never grew big or substantial enough to use for food.

But in some places, when conditions are right with rains and good soil, lambs’ quarters can grow fairly lush. Not up-to-your-chest lush, as they can and often do in lower locations, but up to the thigh at least, with leaves that are substantial enough to be worth your time. This weed is a score!

Wild Spinach Pesto, Garlicky Good

For several years my go-to preparation was cooked as a side dish like spinach. I’d do this when I found enough to bother, because they do shrink down in the pan. Otherwise I’d use them like spinach in other dishes.

This time, however, armed with Dina Falconi’s fantastic book of wild “master recipes,” where a myriad of wild and cultivated ingredients can be substituted in a given recipe, I decided to try my hand at my very first pesto. I used lambs’ quarters for the greens and sunflower seeds for the nuts or seeds. The flavor came out garlicky-nutty good, as to be expected since lambs’ quarters is such a mild green and there was garlic in the recipe.

I was super excited to eat wild pesto by the forkful, and spread it on good, toasted bread for lunch. The best part is that many wild pestos can be born from this basic recipe.

The book, Foraging & Feasting: A Field Guide and Wild Food Cookbook (2013), is by Dina Falconi, an herbalist, forager, and cook based in New York’s Hudson Valley. Falconi masterminded the book, which includes plant maps featuring botanical illustrations by Wendy Hollender for 50 common edible plants, informational charts, foraging how-to’s, and a cookbook of Falconi’s master recipes. The two raised $115,000 on Kickstarter to pay for production and printing costs for the hardcover book, which is available at I will be publishing a more in-depth review. In the meantime, Dina was kind enough to share her recipe:

Wild Green Pesto Master Recipe by Dina Falconi

Makes about 1 cup

Versatile and nutritious, wild green pesto is a gourmet delight and an herb class favorite. I enjoy serving it as a spread on bread. Pesto, typically added to pasta, tastes great topping whole grains and burgers, and in soups, sauces and dressings. Make it creamy by mixing it with equal parts yogurt, crème fraiche, or heavy cream. In this recipe we can use any wild greens that are eaten raw. While some friends make pesto from only dandelion leaf (very bitter) or nettle (which generally needs cooking to chill out the sting), I suggest using half pungent, aromatic plants and half milder tasting ones. If adding bitter flavored plants, include small amounts—about one-half cup per batch. Please note: I usually triple this recipe, multiplying all the ingredients by three.

My first pesto, made with mild lambs' quarters greens, sunflower seeds, oil, and garlic. I followed a master recipe by Dina Falconi to create my yummy concoction.
My first pesto, made with mild lambs’ quarters, sunflower seeds, oil, Parmesan cheese, sea salt, and garlic. I followed Dina Falconi’s master recipe to make it.


  • 2 oz (by weight) hard grating cheese such as Pecorino Romano, cut into chunks (fills about ½ cup)
  • ½ cup nut or seed (preferably soaked and dried); some good choices are sunflower seeds, green pumpkin seeds, hazelnuts, almonds, pecans, and pine nuts
  • 1-2 cloves garlic (less garlic is used than typical pesto recipes so you can taste the flavor of the herbs)
  • 3 cups packed wild greens (edible raw) of choice; if leaves are large, coarsely chop
  • Sea salt to taste


  1. Place cheese in food processor and process until well pulverized.
  2. Add nut or seed and garlic and process until medium-find ground.
  3. Add wild greens and process until mixture is well-minced.
  4. With food processor running, add olive oil until the desired consistency is reached: 1/3 cup oil produces a thicker consistency—nice for spreading on bread, crackers, etc. For a thinner, looser sauce add another ¼-1/2 cup of oil.
  5. Taste first, then add salt if desired.

    Much of the lamb’s quarters that grow in my area have dark burgundy to purple stems and leaf edges. As you mentioned, in lower altitudes they can grow lushly, like a 6 foot tall bush. The leaves tend to get a bit too tough when the plants are that large/old though. I’ve also found that the leaves don’t keep well and will shrivel up within minutes of picking.

  2. Wild Food Girl says

    Hi Dale, thanks so much for that info, especially the point about the burgundy stems and leaf edges. I’ve never had the leaves shrivel up like that. Can I ask what your altitude is?
