In order for produce to be considered as being heirloom, it must come from a plant that is over 70 years old. Heirloom tomatoes have the biggest selection in this category of plants.

Over the last 10 years the most popular heirloom tomato has been the Pink Brandywine. However in the last two years the Caspian Pink has been the top selling heirloom tomato plant.

I will treasure the heirloom.

An heirloom is a familial treasure.

Tomatoes are considered as heirlooms once they have been around for at least 60 years. many heirloom tomato plants have been grown for over 100 years. They must also be able to grow the same type of plant as the seed that was saved.

Organic and heirloom are two different classifications. Seeds are classified as organic if their mother plant was grown without the use of any chemicals. This would include products that would have been put on the soil. An heirloom seed is from a variety that has been around over 70 years.
