Scientific Synonyms:

Description

Helianthus tuberosus is an attractive, robust species of sunflower that can grow to a height of 10'. The upper portion of the plant is divided into multiple stems that are terminated by daisy-like flowers, with yellow rays and orange disks, each spanning up to 3 1/2" across. The leaf characteristics are highly variable, depending on the population, but are essentially lance-shaped, up to 9" long and 4" across, more or less serrated and hairy. The stems are stiff, hairy and typically reddish in color. Aside from its spectacular floral display, Jerusalem artichoke is very popular for its delicious edible tubers. These are rounded, 2" across or more, and can be consumed both raw or cooked.

Cultivation

Jerusalem artichoke is very easy to grow in average garden settings. It is not particular about soil types, is tolerant of dry conditions, and performs best in part to full sun. It should be given plenty of room to grow, because of the sheer size of the plants, and also because of its ability to form large clonal colonies via a robust rhizomatous root system. This species is a prolific bloomer, with flower production beginning in August and extending into October. Very cold hardy. Zones 3-8

Propagation

Propagate by transplanting tubers collected in fall, or by seed.

Additional Notes

Helianthus tuberosus produces large amounts of tubers that are highly nutritious, low in starch, rich in carbohydrates, and with a flavor reminiscent of artichoke, hence the common name. The species is native to the American Great Plains, and has nothing to do with Jerusalem, which is a distortion of the Italian word for sunflower: girasole.
