Tomato ‘Cuor Di Bue’ Seeds | Heirloom Beefsteak Tomato of Liguria

Tomato ‘Cuor Di Bue’ (Coeur de Boeuf), a legendary heritage beefsteak variety from Liguria, Italy, is the ultimate gourmet slicing tomato. Celebrated by chefs and gardeners alike for its superb taste and magnificent, heart-shaped fruits, it produces meaty, dense flesh with very few seeds and a rich, perfectly balanced flavour.​

Weighing 150-180g, these substantial tomatoes are the star of any summer dish. As praised by experts from Le Manoir aux Quat’Saisons to The Guardian, its texture and juiciness are unmatched. An indeterminate (cordon) variety, it promises a generous harvest of these exquisite fruits, ideal for the finest caprese salads, sandwiches, and fresh sauces.​

🌱 Sowing information
Sow seeds indoors in a warm, bright location. Sow 2-3 seeds per pot, about 0.5 cm deep, in a quality seed compost. Thin to the strongest seedling. An early start under protection is essential for developing these large, magnificent fruits.​

☀️ Light exposure
Demands a full sun position. The hottest, most sheltered spot in your garden,such as against a south facing wall,is crucial for achieving the best flavour and ripening in the Irish climate.​

💧 Water needs
Water seedlings regularly. Once transplanted, water deeply and consistently at the base to maintain even soil moisture. Avoid erratic watering to prevent fruit splitting and blossom end rot, which beefsteak types can be prone to.​

🌡️ Germination temperature & time
Seeds require consistent warmth, ideally 18–24°C, for reliable germination. Seedlings typically emerge in 7–14 days. Using a heated propagator is highly recommended for early sowings.​

📏 Plant spacing & final size
Space plants 60–70 cm apart in the ground or in very large, deep containers (minimum 30L). These are vigorous, tall plants that require exceptionally sturdy staking or a reinforced tomato cage from an early stage.​

🌼 Harvesting notes
Harvest when fruits are fully coloured, feel heavy, and have a slight give at the shoulder. For the peak, sun-ripened flavour, allow them to mature fully on the vine. Support heavy trusses to prevent stems from snapping.​
