Potato Fruits Are Toxic,
Despite Looking Like Green Cherry Tomatoes
Extension Consumer Horticulturist, Dept of Horticulture & Landscape
Many Indiana gardeners are experiencing a new phenomenon in their potato patch.
At least, it's new to them. Potato plants may be producing little green fruit,
about the size of a large cherry tomato. These round, green berries are
actually the fruits of the potato plant. It's not surprising that they look like
tomatoes, since both plants are in the nightshade family.
Most gardeners rarely see this fruit form on potatoes in Indiana. Cool temperatures
during long days tend to promote fruiting in potatoes, which explains the increase
in potato fruit this year. Also, some cultivars seem more prone to fruit
formation than others. So some potatoes may be fruiting while others growing
nearby may not.
Potato fruits are high in solanine, a substance that is toxic to humans, particularly
children. Potato fruits should not be eaten raw or cooked, no matter how much
they look like tomatoes!
