Due to Silver’s diabetes we are planning to grow some Jerusalem Artichokes, as they are suppose to be a better starch for a diabetic than standard potatoes. I have as yet to find a reputable seller for them. The only place I have found with them is in the low quality nurseries.
I have a place planned out for them, though a friend just told me that they need well drained soil and the spot I had planned is in a low spot. So I may have to find a better location for them. I am still trying to find out if I could use straw like I do with my potatoes, though I am thinking of using sand and them some compost.
Here is an excerpt on the Sun chokes:
The Jerusalem artichoke, (Helianthus tuberosus L.), also known as sunchoke, can be produced throughout the United States. However, the plant is better adapted to the northern two-thirds of the country than the southern third. Most areas of North Carolina are satisfactory for producing the crop although yields are not as good as in cooler climates where the crop is better adapted. Jerusalem artichokes are also often used for pickling purposes. The fresh tuber tastes like a water chestnut and is used in salads. Tubers can also be cooked like potatoes.
The edible portion of this member of the sunflower family is the tuber or swollen end of an underground stem, which in some respects resembles a potato. However, unlike most starchy vegetables, the principal storage carbohydrate in sunchokes immediately after harvest is inulin rather than starch. When consumed the inulin is converted in the digestive tract to fructose rather than glucose, which can be tolerated by diabetics.
Jerusalem artichokes should not be confused with the Globe artichoke (Cynara scolymus), which is not adapted to N.C. conditions. In globe artichokes, the edible portion is the globular flower.
