Costoluto Genovese Tomato Seeds
Bring the taste of old-world Italy into your garden with the Costoluto Genovese Tomato, a deeply ribbed heirloom variety treasured for its bold, tangy flavor. Originally from the Liguria region of Italy, this tomato has been a staple in Mediterranean kitchens for centuries, known for its high acidity and rich, complex taste that makes sauces and slow-cooked dishes shine.
Culinary Benefits:
Unlike sweeter heirlooms, Costoluto Genovese offers a robust, slightly tart flavor with meaty flesh and fewer seeds. It’s ideal for cooking — the acidity balances beautifully in sauces, soups, and stews. Its ribbed, scalloped shape also makes it a standout for rustic presentations when sliced fresh.
Perfect For:
This tomato is best known for its role in authentic Italian pasta sauce:
-
Slowly simmer Costoluto Genovese tomatoes with olive oil, garlic, onions, and fresh basil.
-
Let the acidity cook down into a thick, aromatic sauce.
-
Toss with al dente pasta and finish with Parmesan for a dish that captures true Italian tradition.
It also excels roasted, grilled, or used in tomato-based soups where depth of flavor is essential.
Growth and Harvest:
Costoluto Genovese is an indeterminate heirloom that produces heavy yields of medium to large, deeply ribbed tomatoes. The fruits ripen to a rich, bright red and often weigh between 7–12 ounces. Expect a long harvest window, ensuring plenty of tomatoes for fresh use and preserving.
Why Choose Our Seeds:
Our premium, non-GMO heirloom seeds are carefully selected for authenticity and flavor. The Costoluto Genovese is a gardener’s favorite for those who love growing true culinary tomatoes with history and tradition behind them.
Growing Tips:
Plant in full sun with nutrient-rich soil, providing sturdy support as the vines grow vigorously. Regular pruning helps increase airflow around the ribbed fruits. For best flavor, harvest fully ripened tomatoes and use them at peak freshness for sauces and cooking.
The Costoluto Genovese Tomato is more than just a tomato — it’s a direct connection to Italian culinary heritage. With its bold flavor and versatility, it’s the perfect choice for gardeners who love making homemade sauces and Mediterranean dishes.
Start indoors 8–10 weeks before last frost. Germinate at 26–30 °C on a heat mat; peppers stall below 22 °C. Pot up to 10–15 cm before hardening off outside after nights stay above 12 °C.
Feed balanced through bloom, then bump potassium for fruiting. Stake taller varieties. More detail in our full Canadian growing guide.
Match the pepper to the technique: thin-walled varieties blister fast in a hot pan; thick-walled ones roast or stuff beautifully; fruit-forward ones make balanced sauces and pickles. The variety's flavour profile is your shortcut — see Choosing the right pepper for a use-case guide.
