Jerusalem artichoke

A plant related to the sunflower that produces edible tubers similar to the potato, with a number of health-promoting properties.

The inulin contained in the Jerusalem artichoke tuber is a prebiotic fibre that supports a healthy gut microbiome. The tuber is also interesting for diabetics, as inulin has hardly any effect on blood sugar levels when eaten. Just two of the many positive properties of this attractive edible sunflower.

Sowing and planting

It's best not to plant the tubers in your vegetable bed but rather along the edge or in another sunny spot, as even the tiniest pieces of tuber will sprout again and could spread throughout your bed. The plant also has some ornamental value and can even serve as a temporary privacy screen, as it grows quite tall.

Harvest and processing

You can harvest the tubers from the end of October and all through winter. As long as the ground isn't frozen, you can keep harvesting right up until the new shoots appear.
You can eat them raw or cooked, and you don't even necessarily need to peel them.
