Tomatoes must meet three criteria before being considered heirloom or heritage tomatoes, according to Taylor's Guide to Heirloom Vegetables. The tomato must grow "true to type" from seeds saved from each fruit; the seed must have been available for more than 50 years, and the tomato must have a history or folklore of its own. The hybrid tomatoes that are more commercially available than heirlooms have been developed to withstand the industry's picking, packing, and shipping processes. Heirloom tomatoes have been bred more for flavor than commercial production.
Brandywine has become a very well known heirloom variety, with folklore to go along with it. The seeds are said to have been collected by generations of Amish farming families in the Pennsylvania valley of the same name. Brandywine tomatoes come in black, pink, yellow and red, with some varieties weighing over 2 pounds each. Yellow brandywines have a potato-shaped leaf. They all grow on indeterminate vines, which means that they continue to grow all summer to a height of 8 to 10 feet.
This tomato is said to have been originally grown by the Cherokee Native American people and it has been popular for over a hundred years. It is known as a relatively disease-free tomato that has a smoky sweet flavor. The tomatoes develop to 12 ounces on indeterminate vines that can reach 12 feet. All heirloom tomatoes grow well in soil that has been amended with organic compost.
