The arracacha is a garden root vegetable originally from the Andes, somewhat intermediate between the carrot and celery. Its starchy taproot is a popular food item in South America — especially in Brazil where it is a major commercial crop.

The name arracacha (or racacha) was borrowed into Spanish from Quechua, and is used in the Andean region. The plant is also called apio criollo (creole celery) in Venezuela, zanahoria blanca (white carrot) in Ecuador, virraca in Peru, and mandioquinha or batata-baroa in Brazil.



The leaves vary from dark green to purple. The roots resemble fat short carrots, with lustrous off-white skin. The interior may be white, yellow, or purple.


The most important part is the starchy root. It cannot be eaten raw, but when cooked it develops a distinctive flavor and aroma that have been described as "a delicate blend of celery, cabbage and roast chestnuts".

The boiled root has about the same uses as boiled potatoes, including side dishes, purées, dumplings and gnocchi, pastries, etc., with the advantage of its flavor and (depending on the variety) its intense color. In the Andes region it is made into fried chips, biscuits, and coarse flour. Because it is highly digestible (due to the small size of its starch grains), its purées and soups are considered excellent for babies and children.

Fresh arracachas keep in the refrigerator for 2 to 3 weeks. 100 grams of arracacha provide about 100 calories (26 g of dry matter, 23 g being carbohydrate, 1.1 g of iron, and less than 1 g of protein). The plant is rich in calcium (four times as much as potatoes).

The yellow variety contains substantial amounts of carotenoid pigments, precursors to vitamin A; to the point that excessive consumption of arracachas may cause yellowing of the skin (a condition that is not considered to be harmful).

The young stems can be eaten cooked or in salads, and the leaves can be fed to livestock.


The plant is very susceptible to viruses and is slow to mature (10-12 months), but requires much less fertilizer input than the potato, and is very lucrative. It was imported into Brazil in the 19th century and has been grown commercially since the 1960s. Brazilian crop improvement programs have developed varieties that grow in seven months.

Harvest season (in the Southern Hemisphere) spans from January to September. The roots must be picked promptly lest they become woody. They have a short shelf life and must reach consumers within a week of harvest. The plant grows west of the Andes at altitudes varying from 200 m to 3600 m, but optimally between 1800 and 2500 m. It is frequently grown with other crops such as maize, beans, and coffee.
