Florida Broadleaf mustard (Brassica juncea) is a popular, fast-growing heirloom, or "cut and come again" variety, known for large, dark green, tender leaves with a mildly spicy, peppery flavor. Ideal for Southern gardens, it thrives in cool-to-mild weather (50-75°F), matures in 25–50 days, and is commonly harvested for both baby greens and large, mature leaves for cooking.
