Ordinary And Unique Trees And Shrubs Starting With The Letter O

There are ordinary and unique plant specimens that start with the letter O. As the list of plant section goes through each letter of the Alphabet, I hope that you will be able to gain knowledge on some popular as well as unique trees, shrubs, flowers, and herbs. Below are eight different species that begin with the letter O.

• Olea - this genus has around twenty species. The Olea is an evergreen tree and also known as the Common Olive. This family is native to the Mediterranean region as well as Africa, Arabia and Himalayan Asia. The trees will grow well in zones eight through eleven in the United States. This group of trees are long lived and they are known for their tiny clusters of white flowers, which are followed by fruit, which are called drupes. These trees like a mild climate but the cooler winter months will encourage more flowering the following season. Olea love the long warm season of summer in their native environment. The fruit has a bitter taste and must go through a process in order to bring about what we know today as olive oil. A very productive tree for providing an ordinary product we all use.
