Pear tomatoes are mild in flavor. Home grown tomatoes have a thicker skin that store bought tomatoes. These tomatoes are delicious fresh with a sprinkle of balsamic vinegar and olive oil. Yellow pear tomato plants may bear small fruits, but the vines themselves can reach as tall as 12 feet. For that reason, the heirloom fruits, which are technically in the cherry tomato class, need a support structure such as a wire cage. Packets contain 15+ seeds in each.
