About Oxheart Tomato
Oxheart Tomato, also known as ‘cuor di bue’ in Italian, is a beloved heirloom variety prized for its large, heart-shaped fruit and rich, meaty texture. These tomatoes are low in seeds, full of flavour, and highly versatile in the kitchen—perfect fresh in salads, cooked down into thick sauces, or sliced and dried for winter storage. The fruit can grow very large and dense, requiring heat to fully mature, making it ideal for greenhouses or sheltered, sunny locations.

Where Can You Grow Oxheart Tomato?
This variety thrives in Zones 3–9 when grown in full sun, ideally in greenhouses or warm, sheltered garden beds. Oxheart is well suited for growers looking to maximise tomato production in short seasons or coastal climates with added protection.

History and Historical Uses
The Oxheart tomato originated in Italy and has become a staple in Mediterranean gardens and cuisine. Known for its excellent flavour and firm flesh, it has long been a favourite for sauces and preserving. Its distinctive shape and dense fruit have also made it popular among heirloom tomato collectors and culinary gardeners.
