Siberian tomato is a variety of tomato. It is called "Siberian,"because it is capable of setting fruit at 38 degrees F; however, it is still not very frost hardy.
Summary
In 1984, William Bonsall introduced the seed for this variety of tomato to the Seed Savers Exchange Yearbook. When the tomato was first domesticated is unknown; although, it was known to grow in Southern Mexico in 500 BC. This variety grows well in most parts of North America.
These tomatoes are very hardy and versatile; therefore, this type of tomato is an earlier-grown form that is best used for canning or processing. They are small, bright red tomatoes, and their plants grow from six to eight feet tall. They are of the heirloom variety of tomato.
