Over 12 million calories per acre can be produced by Jerusalem artichokes, which are a prolific and calorie-dense crop. Often called sunchokes, the primary part of this sunflower-family plant that you eat is its knobby, underground tuber. This versatile ingredient can be enjoyed in many different culinary applications, from soups and roasts to salads.

The average American consumes over 110 pounds of potatoes per year, making it the most frequently eaten tuber by far. So, what is a tuber that we commonly eat? The answer is overwhelmingly the potato, a starchy, nutrient-dense staple enjoyed globally in a myriad of forms, from French fries to baked spuds.

The common pignut, or *Conopodium majus*, is a small, wild plant known to have edible, chestnut-like tubers beneath the soil. For centuries, foragers, including children and wildlife like badgers, have sought out these wild treats, often likened to hazelnuts in taste. However, its identity is easily confused with other, more dangerous plants in the same carrot family.

Originally cultivated by the Aztecs in Mexico, dahlias have a long history as a food source before becoming primarily ornamental. While many gardeners are familiar with their stunning blooms, a lesser-known fact is that both the tubers and petals of this plant are safe for human consumption.

While hundreds of Dioscorea species exist globally, not all of them are safe for human consumption; some are highly toxic and can even be deadly if not properly prepared. The edibility of Dioscorea, the genus that includes true yams, is complex and varies significantly depending on the species and proper detoxification methods. Safe foraging requires careful identification and preparation to avoid consuming poisonous varieties containing toxic alkaloids like dioscorine.

For centuries, certain species of the aquatic arrowhead plant (*Sagittaria*) were a valuable food source for Native Americans, who consumed the starchy, potato-like tubers. However, the popular houseplant also called 'arrowhead' is toxic if ingested, making the question 'Can an arrowhead be eaten?' far more complex and dangerous than it seems.

Approximately 7,000–10,000 years ago, wild potatoes were domesticated in the Andes, but many wild species today are not safe to eat, raising the question: is wild potato vine edible? While some parts of one specific plant, *Ipomoea pandurata*, are edible with proper preparation, others are highly toxic, making accurate identification critical for survival foraging.

Despite its name, the tigernut is not actually a nut, but a small, edible tuber or root vegetable. These ancient tubers have been a dietary staple for thousands of years, with archaeological evidence suggesting they were consumed by ancient Egyptians. Its unique composition is what gives it a sweet, nutty flavor and a powerhouse of health benefits.

According to botanical experts, the Chinese yam, or *Dioscorea batatas*, is one of the few yam species that is non-toxic and safe to be eaten raw. However, unlike many other yams that contain harmful substances in their raw state, you can eat huai shan raw by following specific preparation methods.
