Legendary heirloom known for deep, sweet-savory flavor and beautiful dusky purple color. Vigorous plants produce large, slightly flattened slicers perfect for sandwiches and Caprese. Stake and prune for best airflow and support. Start indoors 6-8 weeks before last frost; transplant to full sun, fertile loam (pH 6.0-6.8). Indeterminate habit sets fruit over a long season. Harvest when shoulders soften and color deepens.
