that's how exactly it works. We got one Italian Tomato (heirloom, indeterminate) from a neighbor and grew it. It grew 10-12 ft tall and bushy. My wife loved it so much, she saved seeds from couple of tomatoes and next year, we grew only that Tomatoes along with other vegetables. And we grew enough to store for the entire year. We are still eating those tomatoes (Frozen) and hope it will last till our this season tomatoes will start coming.
