Another heirloom hybrid from the University of Florida, the Garden Treasure is the perfect slicing tomato. Anyone who's ever tasted a Brandywine fresh off the vine at the peak of summer will fall in love with its meaty, intense flavor that is verging on addictive. This tomato can stand on its own in a sandwich with mayonnaise and thinly sliced red onion, and is perfect on burgers, in salsa, or layered with fresh mozzarella and basil leaves. Unlike a great heirloom, this tomato will store for days at a time at room temperature without cracking or turning to mush. Remember, never refrigerate a tomato, because it destroys the flavor.
