Leonardo Radicchio: A Vibrant, Bolt-Resistant Italian Chicory
Leonardo Radicchio is a widely adapted, sure-heading variety of Italian chicory suitable for all-season production. This vigorous cultivar matures in just 70 days, producing dense, round heads measuring 4-5 inches in diameter. Known for its exceptional bolt resistance and tip burn tolerance, Leonardo stands out as a reliable choice for both commercial growers and home gardeners seeking a consistent crop of this flavorful Mediterranean vegetable.
The brilliant red leaves with striking white veins make Leonardo Radicchio a visually appealing addition to salads and cooked dishes. Its crisp texture and pleasantly bitter flavor profile add depth to culinary creations, while its nutritional content, including high levels of vitamin K and antioxidants, contributes to a healthy diet. This versatile radicchio variety performs well in various climates, making it an excellent option for growers across different regions.
Leonardo Radicchio thrives in full sun but appreciates some afternoon shade in warmer climates. Plant seedlings 18 inches apart in rows, allowing the compact plants to reach a height of 8-12 inches at maturity. This variety’s strong resistance to bolting ensures a longer harvest window, even as temperatures fluctuate. For the best flavor and most vibrant color, harvest Leonardo Radicchio during cooler weather in early spring or fall.
Growing Success Tips:
- Sow seeds indoors 3-4 weeks before the last frost date for an early crop
- Maintain consistent soil moisture to prevent bitterness
- Provide light shade during hot summer days to reduce stress
- Harvest when heads are firm and well-formed for optimal taste and texture
Leonardo Radicchio offers gardeners a reliable, high-quality crop that combines aesthetic appeal with culinary versatility. Whether used raw in salads, grilled, or incorporated into traditional Italian dishes, this radicchio variety delivers consistent results and exceptional flavor.
For sweeter radicchio, consider blanching the heads by covering them with an upturned pot for the last week before harvest.
