We have seen heart-shaped and square fruits in the past. Some media outlets cover them a lot. You could always make your own heart-shaped vegetables and fruits. This Veggiemold set has you covered. You get 5 heart shaped molds to grow cute fruits and vegetables. They enable you to grow heart shaped tomatoes, cucumbers, eggplants, squash and zucchini.
The bundle includes two 3.1 inch heart molds, two 7.9 inch heart molds and one 11.8 heart shaped mold. Each mold comes with a 6 inch twist tie. These will last you a while. Not too expensive either.
