When you hear “edible sunflower,” you probably think of tall mammoth sunflowers and delicious sunflower seeds. However, Helianthus tuberosa, also known as Jerusalem artichoke or sun choke, is a member of the sunflower family that is grown and harvested for its edible tubers, not seeds. Jerusalem artichoke is a perennial growing up to 8 feet (2 m.) tall and wide, and is covered in small sunflower-like flowers throughout the summer. This article will provide information on companion planting with Jerusalem artichokes.
Jerusalem Artichoke Companion Planting
As an ornamental and an edible, Jerusalem artichoke has plant friends or companions in the veggie garden, as well as in flowerbeds. It attracts pollinators, beneficial insects, and birds. However, it also can be prone to aphids. In fact, it is sometimes used as an aphid decoy plant. Jerusalem artichoke can inhibit the growth of potatoes and tomatoes, so it should not be placed near either of them. Another word of caution, the plant can become invasive if not kept in control.
