Why Plant Jerusalem Artichokes?

The Native “Sunroot” of North America

Jerusalem Artichokes (Helianthus tuberosus), also known as Sunroots or Sunchokes, are a versatile and hardy perennial native to North America. Despite the confusing name, they’re not related to Jerusalem or traditional artichokes—they’re members of the sunflower family, producing edible tubers that are both nutritious and delicious. Historically, Native Americans cultivated Jerusalem Artichokes for their starchy tubers, which were an essential food source during winter months. Today, they’re prized by gardeners, homesteaders, and small-scale farmers for their ease of growth, resilience, and high yields.

What Do Jerusalem Artichokes Taste Like?

Jerusalem Artichoke tubers have a unique flavor, often described as a sweet, nutty cross between potatoes and artichokes. When harvested in late fall or early winter, they are crunchy when raw and take on a rich, earthy sweetness when roasted or sautéed. When sautéed we liken their flavor to McDonald's french fries that won't slowly kill you. They’re a great addition to soups, salads, stir-fries, or simply roasted with olive oil and herbs. Their high inulin content makes them an excellent prebiotic food, supporting gut health naturally. Go easy on them at first or you will begin to call them Jerusalem "Fartichokes".

Why Plant Our Jerusalem Artichoke Tubers?

Our Jerusalem Artichokes are grown outdoors in healthy, living soil without the use of herbicides, pesticides, or chemical fertilizers. We focus on producing large, vigorous tubers with strong growth potential for easy transplanting. These tubers are perfect for expanding existing patches, creating new beds, or starting a perennial vegetable garden.

Jerusalem Artichokes are incredibly hardy, can thrive in poor or dry soils, and will naturalize over time, giving you a self-sustaining source of nutritious tubers year after year. They also attract pollinators and beneficial insects with their tall, sunflower-like blooms.

FAQ

What are Jerusalem Artichokes, and why are they called “Sunroots”?

Jerusalem Artichokes (Helianthus tuberosus) are a North American native perennial tuber, part of the sunflower family. Despite the name, they aren’t from Jerusalem and aren’t true artichokes—they’re “Sunroots” because of their sunflower-like blooms and edible underground tubers.

What do Jerusalem Artichoke tubers taste like?

Like a healthy version of a fast-food french fry. These tubers are nutty and slightly sweet, with a flavor somewhere between potatoes and artichokes. They’re crunchy raw and develop a rich, earthy sweetness when roasted, sautéed, or boiled. Perfect for soups, salads, or just roasting with olive oil and herbs.

How do I plant and grow Jerusalem Artichokes?

Plant tubers with visible “eyes” 12–18 inches apart, in rows about 3 feet apart, in full sun to partial shade. They tolerate a wide range of soils, from loamy to sandy or clay, and once established, they’re drought-tolerant and low-maintenance.

How long does it take for Jerusalem Artichokes to produce tubers?

You can expect harvestable tubers in the first year, usually after the plants reach maturity in late fall. Once established, they are perennial, providing tubers for many years with minimal effort.

Are Jerusalem Artichokes good for wildlife?

Yes! The tall, sunflower-like blooms attract bees, butterflies, and other pollinators, while the dense foliage provides shelter for small garden critters. Underground, the tubers are safe from most animals until harvest.

What are the health benefits of Jerusalem Artichokes?

  • Inulin: Supports gut health and helps regulate blood sugar
  • Vitamins & Minerals: Contains iron, potassium, and vitamin C
  • Fiber: High-fiber, low-calorie food for healthy diets
  • Antioxidants: Helps reduce oxidative stress naturally

Can Jerusalem Artichokes take over my garden?

They can naturalize over time if left unchecked, but this is also a benefit: they self-propagate, giving you a sustainable, low-effort perennial crop year after year. Proper spacing and periodic harvesting keep them under control.
