Heirloom Jerusalem Artichoke Seeds - Vegetable Plant

Jerusalem artichoke is a perennial root plant that develops tall stems, broad leaves, and underground tubers during the growing season. Heirloom varieties thrive in temperate climates and perform best in full sun with loose, fertile, well-drained soil rich in organic matter. The plant adapts well to garden beds, raised beds, and naturalized planting areas where consistent moisture and open sunlight support vigorous growth and healthy tuber development.
