Like in the genealogy of human families, sometimes plant families can contain many members that don’t look at first glance to be related at all. For example, in my own family, some of us have medium to dark complexions, brown or black hair and brown eyes. Others, like my sister are blonde, fair-skinned, and have green eyes.

Or, then there is my brother, who before his kids gave him gray hair, was a red-head. His eyes are blue and he is quite freckled.

Such is the case of the over twenty-eight thousand members of the potato plant family. What’s especially unique about this plant family is it’s role in history. In the past, I’ve written about How Potatoes Changed The World.

Here in America, not only did members of the potato plant family change our world (even though they were here first), they literally changed the basic genealogy of the American people. Without the potato plant family, the virtual complexion of American genealogy would be vastly different, for certain members of this plant family were indirectly responsible for mass migrations of people that might not have ever come to our shores.

Like their closely related plant family, the Morning Glory plant family, members of this group are mainly tropical. Besides the White or Irish potato, it includes some surprising members:

Belladonna (Deadly nightshade)

Black nightshade
Chili peppers
Dutura

Eggplant

Goji Berry

Ground Cherries

Henbane

Huckleberry

Flowering Tobacco
Mandrake
Matrimony Vine
Paprika
Pepper varieties (from the small bird’s eye to the large red bell peppers)

Petunias
Thorn Apple (Jimsonweed)
Tomatillo
Tomarillo
Woody Nightshade (Bittersweet)
