But jicama is much healthier and has far fewer carbohydrates. Though you are quite likely to find jicama at your local grocery store, you are much less likely to find it available at your local gardening center. Since the temperature and day length conditions required to mature good quality roots of currently available cultivars do not exist in the United States (except perhaps in the south of Florida), it is unlikely that current cultivars of jicama can be grown successfully in this country.

[28] It oxidizes to rotenolone, which is about an order of magnitude less toxic than rotenone. It was the first described member of the family of chemical compounds known as rotenoids. Yields are in the range of five to seven tons per acre. Variations in the chemical composition and insecticidal properties of the yam bean. The skin is thick and inedible and must be discarded so there's a bit of work involved in peeling.
