But what I don't know much about are the oh so popular heirloom tomatoes. So I did a bit of reading and thought I'd share the basics I learned...


*Tomato experts, Craig LeHoullier and Carolyn Male, have classified heirlooms into four categories:
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.

**Heirloom tomatoes are also divided into fruit size categories:
Heirloom Cherry Tomatoes – small bite-sized or salad sized tomatoes.
Heirloom Paste Tomatoes – meaty flesh with fewer seeds.
Heirloom Slicing Tomatoes – large, round tomatoes also called “beefsteak” tomatoes.
Heirloom Shaped Tomatoes – odd-shaped tomatoes that don’t fit into typical categories.

**And, heirloom tomato color categories:
Red Heirloom Tomatoes – The well-known and popular color for tomatoes.
Orange and Yellow Heirloom Tomatoes – Lower in acid than typical red tomatoes, these heirlooms would be a great choice for anyone suffering from ulcers.
Pink or Purple Heirloom Tomatoes – Second lowest acid content they are similar in flavor to the red tomatoes.
Green Heirloom Tomatoes – Unusual tomatoes that remain green tinted even when fully ripe.
White Heirloom Tomatoes – Often sweeter than others, these are white or near white tomatoes.
Striped Heirloom Tomatoes – Some of the most unusual tomatoes of all these can be red and yellow; green and orange or anything in between.
