Vegetables Jerusalem Artichokes

Organic Jerusalem Artichoke Tubers

Product ID: 511

A unique market offering, Jerusalem artichokes are also known as "sunchokes."

A high-yielding, carefree crop for additional winter sales. This extra-early strain produces large, white, potato-like tubers often weighing over 1/2 lb. each. They store well and can be eaten raw or cooked. The 6–8' tall plants with bright-yellow blooms make an attractive windbreak, helping to prevent soil erosion. Flowers in July and matures over a month before common varieties. Winter hardy in severe cold. Perennial in Zones 3–8. USDA Certified Organic.

Tubers ship in October for fall planting.
At harvest, Jerusalem artichoke tubers are high in inulin, a type of carbohydrate with a very low glycemic load that makes them suitable for individuals with insulin-resistance, such as diabetics, and dieters. The inulin is converted gradually into fructose while the tubers remain in storage, however, at which point the glycemic load of the tuber is more like that of a potato.
SCIENTIFIC NAME: Helianthus tuberosus
CULTURE: As soon as possible after seed pieces are received, break or cut tubers into one- or two-eye pieces of approximately 1-2 oz. each (about 1 1/2" diameter). Plant pieces 4" deep and 12-18" apart in rows 18-36" apart. Do not allow seed pieces to dry out before planting. If you cannot plant them right away, store the tubers in a cool place 34°F (1.1°C). Plants grow best in light or sandy soil, but will also grow in clay soil if organic matter is added. Choose a permanent location as Jerusalem Artichokes are difficult to eliminate once established.
HARVEST: Tubers may be harvested from late summer through late fall. It is best to harvest tubers after several frosts as this improves their flavor.
STORAGE: For later consumption: Tubers may be frozen, refrigerated in perforated plastic bags, or stored in a root cellar in perforated plastic bags or slightly vented containers. Keep tubers damp to prevent shriveling. The next crop can be planted from harvested tubers or leave some in the ground to grow again. For seed stock: keep tubers in a bucket of damp soil in a basement or other cool, damp space. Do not freeze.
SEED SPECS: One lb. of seed pieces (avg. 12 pieces) will plant 12-18'.
