I planted a golf ball sized Jerusalem artichoke (Helianthus tuberosus) in mid March and it was a real success. By September it had reached a height of 18ft and by late October flowered topping over 20 ft. As the weather cooled in early November the flowers faded, the leaves dried and the plant told it’s gardener to cut it down and reap the rewards below. Today I dug out the Jerusalem artichokes and was blown away by how much it had multiplied.
I would definitely plant these again! While I’m pretty new to eating Jerusalem artichokes I’ve read you cook them much like potatoes, either mashed, fried, or baked (preferably in butter). They are high in iron, potassium and fiber. Planted in rich composted soil, with medium to full sun and adequate water, helianthus tuberosus is a easy to grow, and practically care free. Some forethought in setting up some solid supports will make your life easier late summer when they become taller. Staking mid season might lead to damaging the tubers below.
