Jerusalem Artichoke: The Nutritious Superfood for Diabetics

Jerusalem artichokes, often referred to as sunchokes, are one of nature’s most underrated gems. Despite their name, they’re neither from Jerusalem nor related to artichokes. These knobby tubers are actually the edible root of a sunflower species (Helianthus tuberosus), native to North America. With their nutty, slightly sweet flavor and impressive health benefits, Jerusalem artichokes deserve a spot in your kitchen and garden.

What Is a Jerusalem Artichoke?

The Jerusalem artichoke is a perennial plant that produces tall, sunflower-like blooms and a unique tuber that looks a bit like ginger root. Its name is thought to come from the Italian word girasole (meaning sunflower), which was mistranslated as “Jerusalem.” The tuber’s flavor is reminiscent of artichoke hearts, which explains the latter half of its name.

How to Grow and Harvest Jerusalem Artichokes

Jerusalem artichokes are hardy and low-maintenance, making them perfect for beginner gardeners. They thrive in USDA zones 3-9 and prefer well-drained soil and full sun.

1. Planting

• Start in early spring by planting tubers directly into the soil, 4-6 inches deep and 12-18 inches apart.

• These plants grow tall, so choose a location with room for their towering stalks.

2. Caring for Your Plants

• Minimal watering is needed, but consistent moisture helps with tuber formation.

• They are resistant to most pests and diseases, but occasional staking may be required to support their height.

3. Harvesting

• Wait until late fall or early winter after the first frost, which sweetens the tubers.

• Dig carefully to avoid damaging

them. Store in a cool, dry place or leave them in the ground and harvest as needed.
