Celeriac is the same species as celery, but it was bred for its knobby swollen root. Both share the same rich flavor, though celery root has more complexity and sweetness. Celeriac, as a garden plant, has the bonus of being quite hardy and less picky when it comes to climate. 'Monarch' is a common variety known for its uniform roots and excellent flavor, in addition to agronomic qualities that make it easy to grow and resistant to pests.

The roots store well in the cellar. It's best to harvest before the ground freezes. We like to harvest the tops for soup stock, and to use the roots in a range of dishes, from soups and stews to salads and even breads. The roots roast well, fry well, and mash well (adding a wonderful flavor to mashed potatoes). Nate likes to shred the fresh root along with beets and carrots for a simple salad (with nothing but lemon juice as dressing). These seeds were grown for EFN by Kass McKinnon and Clint Freund in Wisconsin.

GROWING TIPS: Starts plants indoors ten weeks before last frost. Transplant to garden early spring after danger of last frost, with 14-18 inches between plants.
