Smallanthus sonchifolius
The yacón (Smallanthus sonchifolius) is a species of daisy traditionally grown in the northern and central Andes from Colombia to northern Argentina for its crisp, sweet-tasting, tuberous roots. Their texture and flavour are very similar to jícama, mainly differing in that yacón has some slightly sweet, resinous, and floral (similar to violet) undertones to its flavour, probably due to the presence of inulin, which produces the sweet taste of the roots of elecampane, as well. Another name for yacón is Peruvian ground apple, possibly from the French name of potato, pomme de terre (ground apple)

Yacón (Smallanthus sonchifolius (Poepp. & Endl.), Syn.: Polymnia edulis, Polymnia sonchifolia) ist eine Pflanzenart aus der Gattung Smallanthus und gehört wie die Sonnenblume (Helianthus annuus) und Topinambur zur Familie der Korbblütler (Asteraceae). Die Yacónknollen haben ein leicht süßliches Aroma und können lange gelagert werden. Die Knollen der Maniok (Manihot esculenta) und die Süßkartoffel (Ipomoea batatas) haben eine gewisse Ähnlichkeit mit den Knollen der Yacón, was zu einer Verwechslung führen kann. Die Knollen müssen vor Frost geschützt werden.

The yacón (Smallanthus sonchifolius) is a species of daisy traditionally grown in the northern and central Andes from Colombia to northern Argentina for its crisp, sweet-tasting, tuberous roots. Their texture and flavour are very similar to jícama, mainly differing in that yacón has some slightly sweet, resinous, and floral (similar to violet) undertones to its flavour, probably due to the presence of inulin, which produces the sweet taste of the roots of elecampane, as well. Another name for yacón is Peruvian ground apple, possibly from the French name of potato, pomme de terre (ground apple). The tuber is composed mostly of water and various polysaccharides.
Traditionally, yacón roots are grown by farmers at mid-elevations on the eastern slopes of the Andes descending toward the Amazon. It is grown occasionally along field borders where the juicy tubers provide a welcome source of refreshment during field work. Until as recently as the early 2000s, yacón was hardly known outside of its limited native range, and was not available from urban markets. However, press reports of its use in Japan for its purported antihyperglycemic properties made the crop more widely known in Lima and other Peruvian cities.
