Yac�n, another great food plant from South America Yacon is a perennial plant grown in the mid-elevation Andes for its crisp, sweet-tasting tuberous root. The texture and flavor have been described as a cross between a fresh apple or pear and watermelon, with maybe a hint of celery, and they are delicious eaten fresh. Yac�n contains inulin, a type of sugar that your body can't digest. This helps keep the overall caloric content of the yac�n low even though it has a sweet taste. The inulin content in yac�n may provide a number of health benefits, including aiding in digestion and promoting beneficial bacteria in your digestive tract while inhibiting harmful organisms. Yac�n can be grown throughout North America. In Northern areas plant after the last frost and harvest after the first few frosts have caused the tops to die back. While usable-sized tubers develop fairly early, they taste much sweeter after some frost. Yac�n has two types of tubers, the edible storage tubers and propagation tubers that should be stored until spring.
