Giant Noble spinach (Spinacia oleracea) is a high-yielding heirloom variety known for its large, tender, dark green leaves, which can grow up to 10 inches long. Maturing in 40-50 days, it thrives in cool seasons and is slow to bolt, making it ideal for spring and fall planting. Rich in iron, calcium, and vitamins A, C, and K, it supports immune and bone health. Versatile and flavorful, it’s perfect for salads, steaming, or freezing, and a favorite for its productivity and ease of growth.
