Pineapple Tomato. Named for its shape, not flavor, the Pineapple tomato is a bi-color beefsteak tomato. Its outer ribbing is reminiscent of a pineapple's ribbed exterior. The tomato's size, too, places it in the category of large tomatoes. 85-90 Days Enormous, uniquely-patterned, yellow-red striped fruits will be the center of attraction. Beefsteak-type fruits easily grow to 5" and larger, and are orange-yellow with red streaks. Fruits have meaty flesh, mild flavor, and no green shoulders. Heavy foliaged plants produce good yields.
