Hey Jimi,
Last year we tried growing a new crop in half-barrel containers filled with old potting soil mix.
They were honestly some of the weirdest-looking tubers I’ve ever seen. Just look at these little guys!
These are Chinese artichokes, also known as crosnes (pronounced crones). Despite their unappetizing appearance, they are highly nutritious—and extremely low maintenance, considering how they thrived in our half-barrels!
Originally cultivated in China and Japan, these tubers made their way to France in the late 1800s, where they became a delicacy and were named after the town of Crosne. While still rare in U.S. gardens, they are slowly becoming more sought-after, especially among chefs who love their crisp texture and versatility.
Are they worth growing?
Chinese artichokes have a crisp texture and mild, slightly sweet flavor, perfect for fresh eating, stir-fries, and salads. They are also high in fiber and antioxidants, and low in calories, offering a healthy alternative to traditional root crops.
Will they sell at your local farmers market? Depending on your market, they may fly or just sit there! You may have to educate your customers on how to use them in the kitchen.
But these crunchy, nutty tubers are gaining popularity in high-end restaurants, where chefs use them fresh, pickled, roasted, or even as a delicate garnish.
Growing tips:
Although we’re still getting the hang of growing these odd tubers, we’ve found they thrive in containers, raised beds, or loose, well-aerated soil with high organic matter.
Loose soil is the key. If your soil is too compact, the tubers may not grow well and will be difficult to harvest. If you have heavy soil,
Jerusalem artichokes might be a better fit, as they have a similar taste to Chinese artichokes.
Zones 7-9: Chinese artichokes are resilient perennials, and will grow aggressively in warm areas—to the point where you might need to keep them from spreading too much!
Zones 4-6: They die back in winter in colder zones but return in spring. A heavy mulch layer will help protect them overwinter.
Zone 4 & colder: You can still grow them as an annual or overwinter them indoors in containers.
If you're looking to grow something unique that chefs are excited about, without taking up a lot of your time, Chinese artichokes (crosnes) are worth a try.
