Yacon

Smallanthus sonchifolius, Peruvian Ground Apple, Bolivian Sunroot

Tender Tuber

An unusual and delicious tuber, widely grown in South America for its crunchy texture and sweet pear-like flavour. Similar in appearance to a sweet potato but with the texture of water chestnuts, yacon makes a fabulous addition to stir fries and salads, or try tossing it in olive oil and roasting with other root vegetables. The juice from yacon tubers can also be simmered to make a sweet syrup similar to honey or maple syrup. Containing an indigestible sugar called Inulin, both the tubers and syrup are suitable for diabetics and yacon syrup is virtually calorie-free! Yacon makes a particularly attractive crop in the garden with bushy growth and large lush leaves which lend an exotic feel to borders or the vegetable plot. Height: 1.8m (6'). Spread: 100cm (39").

Gradually acclimatise yacon plants to outdoor conditions over a period of 7 to 10 days prior to planting outdoors once all risk of frost has passed. Grow yacon in any well drained soil in a sheltered position in full sun. Prior to planting, prepare the soil by adding plenty of well rotted manure or garden compost to improve its structure and fertility. For optimum tuber production plant yacon at a distance of 75cm (30") apart, and cover with fleece until fully established.

Water Yacon plants regularly, particularly during dry periods and especially from mid September when tubers begin to develop. An occasional feed with a general fertiliser and a mulch of well rotted compost will also help to encourage strong growth. Small yellow flowers may be produced in late summer and autumn but these can be left on the plant.


Harvest yacon when the foliage has become frosted and died back in late November and December. Carefully lift tubers taking care not to bruise them. Yacon tubers bury themselves quite deeply in the soil, forming a cluster similar to a dahlia. Once lifted, carefully break away the tubers from the plant. Any damaged tubers should be used promptly or made into syrup as they will rot in storage. Yacon tubers can be stored for several months in paper or hessian sacks, in a cool frost-free shed. Stored tubers will form a thicker skin, which turns a dark brown colour. This skin will need peeling as it becomes bitter over time.
