What Are Sunchokes?
Sunchokes, also known as Jerusalem artichokes or earth apples, are an edible tuber that grows underground, similar to a potato. These versatile veggies are members of the sunflower family, scientifically named Helianthus tuberosa. Sunchokes have a unique texture that blends the best of potatoes and water chestnuts – a crispy exterior and a soft, almost creamy interior.
The Many Names of Sunchokes
Sunchokes have accumulated quite a few nicknames over the years. The name “sunchoke” comes from the plant’s tendency to grow tall and large, shading out and “choking” the sun from the plants around them. They were once called “girasole,” the Italian word for sunflower, since the plant is in the sunflower family. However, over time, “girasole” was mistaken for “Jerusalem,” leading to the name “Jerusalem artichoke,” even though they are not actually related to artichokes.
A Member of the Sunflower Family
Despite their confusing monikers, sunchokes are a distinct and unique member of the sunflower (Helianthus) genus. These tubers are a perennial plant, easily grown in Georgia with minimal care required. Sunchokes can reach up to 10 feet in height and are harvested after the plant finishes flowering in the fall.
“Sunchokes are a versatile and delicious tuber that deserve more recognition. Their mild, nutty flavor and crisp texture make them a great alternative to potatoes in many dishes.”
The History and Origin of Sunchokes
Sunchokes, also known as Jerusalem artichokes, have a fascinating history that can be traced back to Native American cultivation. These versatile tubers are native to eastern North America, with some historians believing they may have originated in the Ohio and Mississippi River valleys.
For centuries, Native American tribes, such as the Iroquois and Lenape, cultivated sunchokes alongside staple crops like corn and beans. These nutrient-rich tubers became an integral part of their diets, providing a valuable food source. Despite the name “Jerusalem artichoke,” sunchokes have no connection to the city of Jerusalem and are not actually a type of artichoke.
The tubers were likely introduced to Europe in the 16th or 17th century, where they gained popularity as a food crop. In France, sunchokes are known as “topinambours,” named after a Brazilian tribe that was exhibiting in the country at the same time. The vegetable’s association with Jerusalem is believed to be a corruption of the Italian word “girasole,” meaning sunflower.
Sunchokes have a long and fascinating history, rooted in their Native American origins and their subsequent journey to Europe and beyond. As these versatile tubers continue to gain attention for their unique flavors and health benefits, their story remains an integral part of their appeal.
| Year | Sunchoke Harvest |
|---|---|
| 1st Year | 70 pounds from 2 transplants |
| 2nd Year | 50 pounds from replanted tubers |
Sunchokes are considered invasive in some areas due to their ability to easily colonize a large area if not contained. However, with proper cultivation and containment, they can be a rewarding and productive addition to any garden.
“The Jerusalem artichoke, although native to America, was first taken to France by Samuel de Champlain in 1616.”
Sunchokes have a long and fascinating history, from their roots in Native American cultivation to their introduction to Europe and their continued popularity today. As these versatile tubers continue to gain attention, their unique story adds to their appeal and makes them a valuable addition to any kitchen.
Growing Sunchokes
Sunchokes, also known as Jerusalem artichokes, are a resilient and prolific perennial crop. With proper cultivation and containment, these versatile tubers can thrive in a variety of garden settings. From planting to harvesting, sunchoke cultivation requires a few key considerations to ensure a bountiful and manageable harvest.
Planting and Caring for Sunchokes
Sunchokes are winter-hardy, allowing for harvesting from October to April whenever the ground is not frozen. They prefer well-draining, silty-clay soil and should be planted 18 inches apart in rows 4 to 5 feet apart to prevent them from growing into thickets. The tubers can be planted in the spring or fall, and they will reliably regrow each season once established.
Sunchokes require minimal maintenance, needing only weekly irrigation to thrive. They can also be grown in large pots or containers, though these will need to be monitored closely to prevent the plants from becoming overly invasive. Harvesting is simple – just lift the tubers with a spading fork when the leaves die back, typically 110 to 150 days after planting.
Containing the Spread of Sunchokes
- Sunchokes are known for their prolific growth, which can make them challenging to control in the garden. To prevent them from becoming invasive, it’s important to take measures to contain their spread.
- One effective method is to grow sunchokes in isolated areas or large pots, as they can quickly take over large spaces if not properly managed. The tubers should be planted at least 4 to 5 feet apart to limit their lateral growth.
- Sunchokes are also self-incompatible, meaning they require genetically diverse clones planted in close proximity to enable seed production. This can help control their spread by limiting their ability to propagate from seed.
- Regularly harvesting the tubers can also help keep sunchoke plants in check, as leaving them in the ground too long can lead to aggressive growth and spread.
By understanding the cultivation needs and growth habits of sunchokes, gardeners can enjoy the many benefits of this versatile and delicious tuber while maintaining control over its proliferation.
