Spring King Tomato, Heirloom Seeds

Spring King Tomato, Heirloom Seeds — The OSU Dry Farm Trial Winner With Split-Resistant 7–10 oz Fruits Late Into Season

Spring King (Lycopersicon lycopersicum) was bred by Tim Peters of Peters Seed and Research in Riddle, Oregon, and scored highly in the Dry Farm Tomato Trials at Oregon State University. This determinate variety produces large, slightly oblate, dark red tomatoes weighing 7–10 oz — blemish-free, split-resistant, and retaining the calyx on the plant at harvest. Healthy, dark green plants provide excellent leaf cover to reduce sun scald. Maintains quality late into autumn. 60–70 days.
