Jerusalem Artichoke
Jerusalem Artichoke (Helianthus tuberosus)
A tall, cheerful sunflower relative grown for its sweet, nutty, versatile tubers
🌿 Jerusalem artichoke, also known as sunchoke, is a vigorous perennial sunflower grown for its knobbly, edible tubers. Despite the name, it isn’t related to globe artichokes — instead, it produces tall stems topped with bright yellow flowers and a generous crop of crisp, sweet, nutty tubers underground. Easy to grow, highly productive, and excellent for winter harvesting, Jerusalem artichoke is a fantastic choice for edible gardens, wildlife areas, and anyone looking to grow reliable, flavourful root crops with minimal effort.
