Large White Ribbed Swiss Chard is a classic, highly productive heirloom prized for its massive, succulent white midribs and broad, dark green crinkled leaves. This variety is exceptionally hardy and heat-tolerant, providing a continuous harvest of tender greens from early spring through the first hard frosts. Often used as a dual-purpose vegetable, the thick stalks can be prepared like asparagus, while the vitamin-rich leaves serve as a mild, earthy alternative to spinach.

TIPS: For better germination, soak seeds in lukewarm water for 24 hours before planting. Swiss chard is a "cut and come again" crop—harvest the outer leaves first to allow the center to continue producing throughout the season. While highly heat-resistant, provide consistent moisture to prevent the stalks from becoming woody or bitter during mid-summer.
