One Plant a Week: Sunchokes
This is the thirty-second post in our series, One Plant a Week, where we learn a new, edible plant every week. That means that if you follow along, you’ll know 52 new plants after only a year of doing this. As our foraging expert guest, Pascal Baudar said on the Wild Fish and Game Podcast, it will make you more of a wild plant expert than 99.99999% of the population.
We recommend you go out and find these plants if they exist in your region. You don’t necessarily have to harvest them; simply familiarize yourself with them and get to know them well. See them in their different phases of life, in different terrains and conditions. See who else likes to eat them (Bears? Squirrels?), pollinate them (Butterflies? Hummingbirds?), or use them (Nesting birds? Muskrats?). Use plant ID apps, along with foraging/ID books, online resources, and mentors to teach yourself about them more and to get comfortable enough with them that you can ID to 100% accuracy.
Then, if you feel confident enough, bring some home and try preparing some to eat. Try doing this with different specimens in different stages of life to see when it is best to harvest them. Knowing these plants through and through will transform the way you interact with the outdoors, as well as the way you see food. A warning though: this is an addictive hobby!
An additional warning: Plant ID apps are not 100% accurate, and you should not be eating ANYTHING wild unless you are 100% sure that it is safe to do so. Do not rely solely on one source for your information (including us), and do not eat anything unless you’ve properly identified it.

This Week is All About Sunchokes!
Sunchokes (Helianthus tuberosus), also called Jerusalem artichokes, are knobby, underground tubers from a tall North American sunflower. Despite their misleading name, they have no relation to artichokes or Jerusalem—the name comes from a mix of European misinterpretation and culinary history. These tubers are crisp and nutty when raw, with a sweet, earthy flavor when roasted or boiled.
Indigenous peoples cultivated sunchokes for centuries, long before European settlers arrived. They were a staple crop across much of eastern North America, valued for their productivity, versatility, and ability to thrive in poor soils. Early colonists quickly adopted them as well, exporting the plant to Europe, where it briefly rivaled the potato in popularity.
For modern foragers and gardeners, sunchokes are a true gift: a perennial vegetable that grows abundantly, stores well in the ground, and provides nutrition through the colder months. Their adaptability makes them one of the most accessible wild tubers for beginners.
Description
Sunchokes are members of the sunflower family (Asteraceae). Above ground, they grow as tall, rough-stemmed plants 6–10 feet high, with lance-shaped leaves and bright yellow sunflower-like blooms that appear in late summer to fall.
Below ground, the plant produces irregular, knobby tubers, usually tan or reddish-brown, resembling small ginger roots. These tubers can spread aggressively, forming colonies that persist year after year.
Lookalikes are few, but other sunflower species may grow in the same area. Digging for tubers is the surest way to identify sunchokes: no other native sunflower produces such edible, starchy storage organs.
Edibility
The tubers are the edible prize of the sunchoke. They can be eaten raw, where they are crunchy and slightly sweet, or cooked, which softens them and brings out a nutty, artichoke-like flavor. Unlike potatoes, they contain inulin rather than starch, which can cause digestive discomfort in some people if eaten in large amounts.
Nutritionally, sunchokes are rich in fiber, iron, potassium, and thiamine. Their inulin content makes them a lower-glycemic alternative to potatoes, offering energy without spiking blood sugar. Indigenous peoples roasted, boiled, or dried the tubers, often using them as a staple carbohydrate through the winter months.
Ten Recommended Uses
1. Roasted sunchokes – Toss with oil and roast until caramelized.
2. Mashed sunchokes – Cook and mash as a potato alternative.
3. Sunchoke chips – Slice thin and fry or bake into crispy chips.
4. Soups – Puree into creamy soups with leeks or wild greens.
5. Pickled tubers – Preserve in vinegar brine for tangy snacks.
6. Gratin – Layer with cream and cheese, bake until bubbling.
7. Fermented sunchokes – Lacto-ferment for probiotic-rich flavor.
8. Raw salads – Shave thin into slaws for a crisp texture.
9. Hash or skillet fry – Dice and fry with onions and wild game.
10. Flour substitute – Dehydrate and grind into a flour for baking blends.
Harvesting and Processing Tips
Collecting
Dig tubers in late fall through early spring, after the plant has died back. Frost sweetens the flavor, making late fall or winter ideal for harvesting. Look in open fields, forest edges, or riverbanks where stands of tall sunflowers grew the previous season.
Processing
Scrub tubers well to remove dirt, as their knobby shapes can trap soil. Peel if desired, though the skin is thin and edible. Slice, chop, or leave whole depending on the recipe.
Storage
Tubers can be left in the ground until needed, as long as the soil isn’t frozen solid. Freshly dug tubers keep about two weeks in the refrigerator. For longer storage, keep in a cool root cellar packed in damp sand, or slice and dehydrate for flour.
