🍅 Italian CUORE DI BUE Tomato Seeds

Price for Package of 10 seeds.

🍅 Italian CUORE DI BUE Tomato Seeds produce large, distinctive oxheart-type tomatoes from the Riviera selection, known for their unusual bottom-heavy shape, dense flesh and excellent flavor. The name Cuore di Bue is Italian for “oxheart”, and this selection offers an attractive variation of the classic oxheart tomato type.

The fruits have a characteristic pouch-like shape with a gathered upper section and can reach approximately 3.5 inches (9 cm) wide and 4 inches (10 cm) long. Individual fruits weigh just under 0.5 lb (approximately 225 g). The skin develops a lustrous orange-red color when ripe, while the interior has dense, meaty flesh with relatively little watery gel.

Cuore di Bue is an indeterminate tomato, meaning the plant continues growing and producing new flowers and fruits throughout the growing season. The variety matures in approximately 85 days and is particularly valued as a sauce and cooking tomato because of its dense flesh. Current specialist seed sources confirm the 85-day maturity, Riviera selection, large oxheart-type fruits and indeterminate growth habit. :contentReference[oaicite:0]{index=0}

🌡️ Temperature Resistance and Cold Hardiness

Italian CUORE DI BUE is a warm-season tomato and is not frost tolerant. Tomatoes require warm growing conditions for healthy vegetative growth, flowering and fruit development.

Ideal growing temperature: approximately 21–27°C (70–80°F).

Germination temperature: approximately 21–24°C (70–75°F).

Cold tolerance: Low.

Frost tolerance: None. Protect seedlings and mature plants from freezing temperatures.

Plant outdoors only after the danger of frost has passed and nighttime temperatures have become reliably warm. Cold conditions can severely slow growth, flowering and fruit production.

The variety is especially appreciated for its low-water, meaty texture. Specialist tomato sources describe Riviera as having very little gel, making it particularly useful for stuffing and sauce production. :contentReference[oaicite:1]{index=1}

🌞 Growing Conditions

Light: Full sun.

Soil: Fertile, rich, well-drained soil with good organic matter.

Position: Warm and sheltered with good air circulation.

Water: Maintain consistent moisture throughout the growing season.

Choose a location that receives several hours of direct sunlight every day. Good sunlight is particularly important for an indeterminate tomato because the plant continues developing foliage, flowers and fruit throughout the season.

🌱 Sowing Instructions

Sowing Time: Start seeds indoors approximately 6–8 weeks before the last expected frost.

Sowing Depth: Approximately 5–6 mm (1/4 inch).

Germination Temperature: Approximately 21–24°C (70–75°F).

Germination Time: Usually approximately 6–14 days under suitable conditions.

Sow the seeds in a quality seed-starting compost and cover lightly. Keep the growing medium evenly moist but not saturated. Place the seed tray in a warm, bright location until seedlings emerge.

🪴 Transplanting

When seedlings are large enough to handle and have developed their first true leaves, transplant them carefully into individual pots.

Grow the young plants under warm, bright conditions until they are strong enough to be hardened off. Gradually acclimatize them to outdoor conditions before planting into the final growing position.

Do not plant outside while there is still a significant risk of frost.

🪵 Support and Training

Italian CUORE DI BUE is indeterminate and therefore requires strong support. Use a tall stake, sturdy tomato cage, trellis or other suitable support system.

The large fruits can place considerable weight on the branches, so supporting the plant from an early stage helps prevent stems from bending or breaking.

Tie the main stems loosely to the support as the plant grows. Regular support is particularly important when the plant begins carrying multiple large fruits simultaneously.

✂️ Pruning and Maintenance

Because the variety is indeterminate, unwanted side shoots can be removed when using a controlled training system. Plants may be trained to one or several main stems depending on the available growing space.

Remove damaged or yellowing leaves and maintain good airflow around the plant. Avoid excessive removal of healthy foliage because the leaves are essential for photosynthesis and fruit development.

💧 Watering

Water deeply and regularly throughout the growing season, particularly during flowering and fruit formation.

Try to maintain relatively even soil moisture. Alternating between very dry and excessively wet soil can place unnecessary stress on the plant and may contribute to fruit quality problems.

Water around the base of the plant rather than repeatedly wetting the foliage, especially in humid conditions.

🌱 Feeding

Feed young plants with a balanced fertilizer during vegetative growth. Once flowering begins, use a fertilizer formulated for tomatoes and fruiting vegetables.

Avoid excessive nitrogen because it can encourage excessive foliage and delay or reduce fruit production.

🐝 Pollination

Tomatoes are naturally self-pollinating. Good airflow and movement of the flower clusters can assist pollen transfer.

When plants are grown in a greenhouse with limited airflow, gently shaking the flower clusters can help improve pollination and fruit set.

🍅 Harvesting

Italian CUORE DI BUE tomatoes should be harvested when the fruits have developed their characteristic mature orange-red color and begin to soften slightly.

Allowing fruits to ripen properly on the plant generally provides the best flavor. Harvest regularly as fruits mature to encourage continued production from the indeterminate plant.

The variety reaches maturity in approximately 85 days under suitable growing conditions. :contentReference[oaicite:2]{index=2}

🍝 Culinary Uses

Cuore di Bue is particularly valued for its dense, meaty flesh and rich flavor. It is an excellent choice for tomato sauces because the fruit contains relatively little watery gel.

The large fruits are also excellent for:

Fresh tomato salads, sandwiches, slicing, stuffing, cooked dishes, sauces and homemade tomato preparations.

The combination of large fruit size, dense flesh and rich flavor makes this variety especially attractive to gardeners who want a versatile tomato for both fresh eating and cooking.

🇮🇹 Italian Oxheart Tomato

The name Cuore di Bue literally means “oxheart” in Italian and refers to the distinctive heart-like shape associated with this tomato type.

The Riviera selection is an exotic interpretation of the oxheart form, producing large fruits with a characteristic bottom-heavy shape. Italian seed and tomato references also describe Riviera selections as indeterminate and producing large, fleshy fruits with excellent eating quality. :contentReference[oaicite:3]{index=3}

🌿 Sauce and Processing Quality

One of the strongest characteristics of Italian CUORE DI BUE is its suitability for sauces and cooking. The dense flesh means that the fruit contains less excess liquid than many juicy slicing tomatoes.

This makes the variety especially useful for gardeners who want to grow tomatoes for homemade sauces while still having a large, flavorful tomato suitable for fresh eating.

🌡️ Heat and Cold Management

Provide warm conditions during the growing season and protect plants from cold nights. If temperatures fall significantly, young plants may stop growing temporarily and fruit production can be reduced.

In cooler climates, growing Italian CUORE DI BUE in a greenhouse or polytunnel can provide a longer growing season and more reliable fruit production.

During periods of extreme summer heat, maintain consistent irrigation and provide adequate airflow around the foliage.
