It is called Vivipary, Latin for Live Birth. It is the term for plants that begin growing while still inside or attached to the mother plant.It is common in certain varieties of tomatoes, peppers, apple, pears and some citrus but I have never seen it myself.
Vivipary happens when the hormone controlling the seed dormancy is exhausted or runs out, letting the seed grow in the moist environment inside the fruit. This warm, moist environment is perfect for germinating seed to grow. If the tomato was left uncut in the warm conditions, the new plant sprout would eventually poke through the skin of the now decomposing tomato. These new plants can be potted up and grow into a large tomato plant and even produce tomatoes. The tomatoes will not be a clone of the mother plant, because it grew from a seed that had to be pollinated by another tomato flower, introducing new parent genes into the seed that will produce the new plant. The tomatoes off of the plant are entirely edible and quite possibly delicious.
