Sweet potatoes come from the same family as Morning Glory and the genus Ipomoea. There are a number of different varieties, including orange, purple and white. The orange one is called Beauregard and is probably the most popular. NUTRITION Sweet potatoes are low in fat and are virtually cholesterol and sodium free. They are an excellent source of vitamin A, protein and fibre and also contain good amounts of vitamin C, E and B6, folic acid, potassium, calcium, magnesium, iron, copper, thiamine, riboflavin, niacin and beta carotene. In fact, they could be called a super food. PLANTING You can use a sweet potato from the green grocers, but to be sure of certified disease free roots you need to buy from a reputable supplier. Goodman’s Seeds sell Beauregard Sweet Potato tubers at Bunning’s for about $8. The Diggers Club also sells purple and white varieties at various times. Garden Express in Monbulk will also post the tubers out.
