The Siberian tomato is one of the heirloom tomato varieties from Russia. It is unusual in that it can set fruit in cool weather (reportedly as low as 38˚F). In fact it is one of the earliest ripening varieties you'll find. Because it is a determinate plant, it is a good choice if you are planning on growing tomatoes in pots.
The fruit grows in clusters on sturdy, bushy stalks. This variety produces a large number of three- to five-ounce brilliant red, flavorful fruits. Not surprisingly, the Siberian is popular in Alaskan gardens, and is an excellent choice for any region with a shorter, cooler growing season.
I recommend buying Siberian Red tomato seeds at TomatoFest because not only do they specialize in heirloom tomato seeds that are certified organic, but their service is great and their staff friendly.
