An heirloom tomato (also called heritage tomato in the UK) is an open-pollinated, non-hybrid heirloom cultivar of tomato. They are classified as: family heirlooms, commercial heirlooms, mystery heirlooms, or created heirlooms. They usually have a shorter shelf life and less disease resistance than hybrids. They are grown for a variety of reasons: for food, historical interest, access to wider varieties, and by people who wish to save seeds from year to year, as well as for their taste.[1]


Many heirloom tomatoes are sweeter and lack a genetic mutation that gives tomatoes a uniform red color at the cost of the fruit's taste.[2] Varieties bearing this mutation, which have been favored by industry since the 1940s, feature fruits with lower levels of carotenoids and a decreased ability to make sugar within the fruit.[3]

Heirloom tomato cultivars can be found in a wide variety of colors, shapes, flavors and sizes. Some heirloom cultivars can be prone to cracking or lack of disease resistance. As with most garden plants, cultivars can be acclimated over several gardening seasons to thrive in a geographical location through careful selection and seed saving.

Some of the most famous examples include Amish Paste, Aunt Ruby's German Green, Bananna Legs, Big Rainbow, Black Krim, Brandywine, Cherokee Purple, Chocolate Cherry, Costoluto Genovese, Garden Peach, Gardener's Delight, Green Zebra, Hawaiian Pineapple, Hillbilly, Lollypop, Marglobe, Matt's Wild Cherry, Mortgage Lifter, Mr. Stripey, Neville Tomatoes, Paul Robeson, Pruden's Purple, Red Currant, San Marzano, Silvery Fir Tree, Three Sisters, and Yellow Pear.

Seed collecting[edit]

Heirloom seeds "breed true," unlike the seeds of hybridized plants. Both sides of the DNA in an heirloom variety come from a common stable cultivar. Heirloom tomato varieties are "open pollinating", and cross-pollination is common without human intervention.

Heirloom seeds can be easily collected and usually almost all seeds will continue to show the traits of the original seed because this family of tomatoes almost always self-pollinates. Dramatic cross-pollination may occur in the presence of pollinating insects during flowering. Collecting heirloom seed is as easy as picking ripe tomatoes, chopping or mashing into a jar till less than half-full, filling with water, shaking from time to time and allowing to decompose for 1–6 days until seeds sink to the bottom, then rinsing until the seeds are clean, and drying. This decomposition is beneficial because it discourages transmission of diseases to the seed, the drying promotes better germination, and because the seeds are easier to separate when they are clean.
