Add a touch of Italian flavor to your garden with Costoluto Fiorentino tomatoes, a beefsteak variety with a deep, rich flavor and a distinctive, irregularly ribbed shape. This variety is semi-determinate, growing to a very manageable height of 3 to 5 ft, and requires minimal pruning. They thrive in full sun and well-drained soil rich in nutrients. Like all tomatoes, theyre also high in vitamin C and antioxidants!
