Yakon

Smallanthus sonchifolius

'Yakon' is a plant in the Polymnia genus with a scientific name of Smallanthus sonchifolius. Mature bloom diameter is on average approximately 2.0 cm (0.78 inches). Yakon grows as an annual/perennial and is a flowering edible vegetable. Being an annual / perennial plant, it tends to grow either as a single season plant, or a plant that can stay in your garden for many years. Try planting Yakon if you'd like to attract bees to your garden.

Yakon is normally fairly low maintenance and is normally quite easy to grow, as long as a level of basic care is provided throughout the year. Being aware of the basic soil, sun and water preferences will result in a happier and healthier plant.

How to grow Yakon

Will benefit from staking in windy areas.

Keep in mind when planting that Yakon is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside.

Growing Yakon from seed

Yacon is generally grown from propagative tubers rather than seed. Seed can be started using the same method that you would for sunflower.

Transplanting Yakon

In mild climates, propagules can be left in the ground over the winter. Otherwise, they can be stored indoors in a cool, dry spot and planted out in spring once risk of frost has passed.

Harvesting Yakon

Plants will generally continue to grow until killed by frost, so harvest is best delayed as long as possible. Two types of tubers are produced: smaller, irregular shaped propagules that can be used to start new plants and large cylindrical storage tubers that are eaten.

Seed Saving Yakon

Two varieties are required to produce seed. Seed matures slowly and a long season may be required to save seed successfully.
