The '''Yacón''' is a [[perennial plant]] grown in the [[Andes]] of [[Perú]] for its crisp, sweet-tasting [[tubers]]. The texture and flavour have been described as a cross between a fresh apple and watermelon which is why it is sometimes referred to as the apple of the earth. The tuber is composed mostly of water and [[fructooligosaccharide|fructo-oligosaccharides]]. It has recently been introduced into farmers' markets and natural food stores in the [[United States|US]].
Commonly called "[[jicama]]" in Ecuador, yacón is sometimes confused with this unrelated plant. Yacón is actually a close relative of the [[sunflower]] and [[Jerusalem artichoke]]. The plants produce propagation roots and storage tubers. Propagation roots grow just under the soil surface and produce new growing points that will become next year's aerial parts. These roots resemble Jerusalem artichokes. Storage tubers are large and edible.
These edible tubers contain [[inulin]], an indigestible sugar, which means that although they have a sweet flavor, the tubers contain fewer [[calories]] than would be expected.
Yacón plants can grow to over 2 meters in height and produce small, yellow inconspicuous [[flower]]s at the end of the growing season. Unlike many other root vegetables domesticated by the Indigenous Peoples of the Andes ([[olluco]], [[oca]]), the yacón is not photoperiod sensitive, and can produce a commercial yield in the tropics.
==Cultivation==
Yacón can easily be grown in home [[garden]]s in climates with only gentle frosts. It grows well in southern [[Australia]], [[Tasmania]] and [[New Zealand]], where the climate is mild and the growing season long. It has recently been introduced to the [[Philippines]], and is now widely available in markets.
While aerial parts are damaged by frost, the roots are not harmed unless they freeze solid. Yacón is a vigorous grower much like Jerusalem artichokes. The plants grow best with fertilization.
After the first few frosts the tops will die and the plants are ready for harvest. It is generally best to leave some in the ground for propagating the following spring. Alternatively, the propagating roots can be kept in the refrigerator or buried away from frost until spring. While usable-sized tubers develop fairly early, they taste much sweeter after some frost.
===Propagation===
Propagation roots with growing points can be planted in a well-dug bed in early spring, near the time of the last expected frost.
