The jicama originated in Mexico and central America. The root's exterior is yellow and papery, while its inside is creamy white with a crisp texture that resembles raw potato or pear. The flavor is sweet and starchy, reminiscent of some apples or raw green beans, and it is usually eaten raw, sometimes with salt, lemon, or lime juice, and chili powder. It is also cooked in soups and stir-fried dishes. Jícama is often paired with chilli powder, cilantro, ginger, lemon, lime, orange, red onion, salsa, sesame oil, grilled fish, and soy sauce. It can be cut into thin wedges and dipped in salsa. In Mexico, it is popular in salads, fresh fruit combinations, fruit bars, soups, and other cooked dishes. In contrast to the root, the remainder of the jícama plant is very poisonous; the seeds contain the toxin rotenone, which is used to poison insects and fish.

Jícama is high in carbohydrates in the form of dietary fiber (notably inulin).It is composed of 86–90% water; it contains only trace amounts of protein and lipids. Its sweet flavor comes from the oligofructose inulin (also called fructo-oligosaccharide), which is a prebiotic. Jícama is very low in saturated fat and sodium. It is also a good source of vitamin C.

The jícama vine can reach a height of 4–5 m given suitable support. Its root can attain lengths up to 2 m and weigh up to 20 kg. The heaviest jícama root ever recorded weighed 23 kg and was found in 2010 in the Philippines (where they are called singkamas). Jicama is frost-tender and requires 9 months without frost for a good harvest of large tubers or to grow it commercially. It is worth growing in cooler areas that have at least 5 months without frost, as it will still produce tubers, but they will be smaller. Warm, temperate areas with at least 5 months without frost can start seed 8 to 10 weeks before the last spring frost. Bottom heat is recommended, as the seeds require warm temperatures to germinate, so the pots will need to be kept in a warm place. Jicama is unsuitable for areas with a short growing season unless cultured in a greenhouse. Growers in tropical areas can sow seed at any time of the year. Those in subtropical areas should sow seed once the soil has warmed in the spring.
