Big Rainbow Tomato is a stunning heirloom beefsteak known for its beautiful multicolored flesh and outstanding sweet, mild flavor. Fruits are large and eye-catching, typically 16–24 oz each, with yellow skin and vibrant red marbling throughout the interior. Plants are indeterminate, producing fruit over a long season once established. With its juicy texture and striking slices, Big Rainbow is a favorite for fresh eating, sandwiches, and showcasing in summer salads.
