Jerusalem Artichokes: Nutty Delight or Invasive Garden Thug 2026

Jerusalem artichokes are a nutty and delicious crop that can easily run rampant in your garden if left unchecked. These tall, leggy plants from the sunflower family produce edible tubers underground, but their aggressive growth habit and digestive challenges have earned them a mixed reputation among gardeners.

What Are Jerusalem Artichokes?

Despite their name, Jerusalem artichokes are entirely unrelated to globe artichokes. They are part of the sunflower family and are grown for their underground tubers, which have a nutty, slightly sweet flavor. The plants produce bright yellow flowers on tall stems, making them an attractive addition to the garden.

However, their beauty belies a fiercely invasive nature. Once planted, Jerusalem artichokes are notoriously difficult to eradicate, as they spread rapidly through their tubers. This vigorous growth is both a blessing and a curse, depending on your gardening goals.

Why Jerusalem Artichokes Are Rarely Seen

Considering how easy they are to grow, it's intriguingly rare to see a crop of Jerusalem artichokes. There are two main reasons for this. First, the tubers can be hard to digest, earning them the nickname "fartichokes." They contain a carbohydrate called inulin that can be tough on the gut, leading to gas and bloating if eaten in large quantities.

Second, once you've planted them, you've probably got them forever. Jerusalem artichokes spread aggressively and can quickly take over a garden bed. Their rampant growth habit means they require careful management to prevent them from becoming a nuisance.

The Digestive Challenge: Why They're Called Fartichokes

Jerusalem artichokes contain inulin, a type of carbohydrate that humans cannot fully digest. When it reaches the large intestine, it ferments and produces gas, which can cause discomfort and bloating. This effect is why they've earned the unflattering nickname "fartichokes."

To minimize digestive issues, it's recommended to cook them well and introduce them into your diet gradually. Some people with robust digestive systems can eat them raw, but for most, cooking helps break down the inulin and makes them easier to tolerate.

Growing Jerusalem Artichokes: A Double-Edged Sword

Jerusalem artichokes are incredibly easy to grow and can thrive in a variety of conditions. They are often planted on slopes to help absorb excess water and prevent erosion, as their tubers form a dense network that holds soil in place. In full sun, they grow vigorously and produce abundant flowers.

However, this vigor can become a problem. The plants spread rapidly through their tubers, and even a small piece left in the ground can sprout into a new plant. If you want to grow them, be prepared to manage their spread carefully, perhaps by containing them in raised beds or harvesting all tubers diligently.
