What is an Heirloom Tomato?
An heirloom is generally considered to be a variety that has been passed down, through several generations of a family because of it’s valued characteristics.
Commercial Heirlooms: Open-pollinated varieties introduced before 1940, or tomato varieties more than 50 years in circulation.
Family Heirlooms: Seeds that have been passed down for several generations through a family.
Created Heirlooms: Crossing two known parents (either two heirlooms or an heirloom and a hybrid) and dehybridizing the resulting seeds for how ever many years/generations it takes to eliminate the undesirable characteristics and stabilize the desired characteristics, perhaps as many as 8 years or more.
Mystery Heirlooms: Varieties that are a product of natural cross-pollination of other heirloom varieties.
How cool is that!
