Zolotye Kupola is a really pretty canary yellow oxheart tomato that will light your garden up when it is fully ripened. Its wispy leaves and skinny vines can be very deceptive in that they sometimes look like they are not going to make it. But true to the oxheart’s spirit, they produce good amounts of tomatoes that can reach 24 ounces. Tomatoes begin to ripen about 80 days after transplant. They are mild and sweet and perfect for sandwiches, sauces, fresh eating, and cooking.
