Radishes

Radishes deliver the fastest turnaround in gardening, going from seed to plate in as little as 25 days — outperforming #6 Basil and every other common vegetable by at least a week. Cherry Belle and French Breakfast varieties are foolproof, thriving in cool weather that halts slower crops, and their peppery crunch adds punch to salads and tacos. A single seed packet costs under $3, yields dozens of roots, and they fit into tiny gaps between slower neighbors. For impatient beginners needing an instant win, radishes provide a 100% success rate when compared to the typical 50-60 day wait of bell peppers.
