History and Origin of the Variety
Historical Origin
Arbuznyi is a remarkable heirloom variety native to Russia, where it has been cultivated for generations as part of the rich agricultural heritage of Black Russian tomatoes. Its name literally means "like a watermelon" (арбузный), referring to the distinctive green stripes that run from the shoulders to the base of the fruit, creating a unique visual pattern reminiscent of the surface of a watermelon.
This variety is part of the Russian tradition of developing dark or "black" tomatoes, characterized by their intense and complex flavors. It was preserved by Russian farmers and gardeners over the centuries, passed down from generation to generation as a family treasure. Its arrival in the West is due to the efforts of seed preservationists who recognized its unique genetic value and exceptional culinary quality.
