Jerusalem artichokes are a relative of the sunflower, and like sunflowers, they grow tall – up to 3 metres in height. The flowers of Jerusalem artichokes are much smaller than a sunflower, with delicate yellow petals surrounding a yellow centre.

The tubers of Jerusalem artichokes are edible and have a nutty flavour. They can be turned into soups and sauces, or mashed and boiled just like potatoes.
