What is a hybrid tomato? Its the result of taking two other tomato varieties and cross pollinating them, resulting in a better tomato. While they may not be as sweet as an heirloom, hybrid tomatoes are easier to grow and offer improved disease resistance. Along with being hearty producers, hybrid tomato plants also handle extremes better, making them the first choice for many gardeners. All of our Hybrid Tomato Plants for sale are grown organically and shipped with very well-established root systems. We guarantee them to arrive alive and thriving.
