Olive

 Olive is a small, oval-shaped fruit that typically ranges in color from green to black when ripe. It's commonly used in cooking and for producing olive oil. 

The taste varies from mild to tangy depending on the variety and processing method. The fruit is often brined, cured, or pressed to extract its oil. 

Olive trees are evergreen and have a distinctive silvery-green foliage, contributing to their aesthetic appeal in landscapes.
