This unique tomato is producing fruit which is in the growing stage not yet ripe. At first glance they look like eggplant with a jet shiny black color at the portion exposed to Sun and perfectly spherical. The underside not exposed to Sun is still green. Closely related to Indigo Rose Tomato.

The Indigo tomatoes will be purple where exposed to light and they tend to have a purple to black crown. They are ripe when their color changes from a shiny blue-purple to a dull purple-brown. The fruit also softens similarly to regular tomatoes, and the bottom of the tomatoes will turn from green to red when ripe.

Ripe when the bottom of the fruit turns red. This is away from the Sun direction. The plant is prolific, and the fruit is perfect with no blemishes. The taste of the fruit is pleasant. Size is about golf ball dimensions. A bowl would be attractive at a dinner setting.
