Plants ordered now will ship Late May.

Yacon, Crystal, (Polymnia sonchifolia) potted plant, organic

$10.00

Family:  Aster (Asteraceae)

Zones 7 to 12.  May be grown in cooler zones as a summer annual–dig tubers after first frost.

Tuberous perennial native to S. America, a heavy feeder that prefers full sun and rich soil, attaining 5 feet tall and equally as wide, with multiple stalks. The secondary tubers may be dug in the fall, and they are large, weighty and productive, rich in fructose and inulin, crisp and delectable.  A traditional Andean food.  After digging the tubers, age them in a cool, dark place for a week or two before eating–they develop their sugars during this resting period, becoming internally almost crystalline.  Don’t be put off by wrinkly skin–they are delicious!  Aerial parts contain 17% protein, making them an excellent feed for livestock. The plants are bold and tough, with decorative, winged leaves, preferring full sun and regular garden soil. Plants reach maturity in 6 to 7 months, flowering bright orange.  This is a choice cultivar, crunchy and sweet. The primary photo is of the actual storage tuber (the edible part).  In the gallery, I have placed photos of the plant as it grows, and of the crown portion (the reddish part used for propagation purposes).   Space plants 3 feet apart.

    At what low temperature will these tolerate? I am in zone 6 and successfully grow some zone 7 plants with mulching and frost covers.

      Hello Joy, Yacon does like to be mulched and can be grown anywhere in the USA as a summer annual. You might well get the roots/crown/tubers to overwinter with protection in a Z 6, although I think a better approach would be to harvest the tubers after first frost and use them. That’s how most of us proceed with the plant, and with a cold greenhouse, you can pot up the crown and overwinter in the greenhouse, then chop it up and plant to the summer garden come spring.

  2. Question

    I assume you are replacing the Morado variety that was on my wait list with this Crystal variety that I mistakenly ordered after being notified that “it” was now available? Will you not be offering Morado again?

      Hi! This year we’re growing Crystal because it is sweeter than Morado. The yield is similar. Richo
