Coconut Details
The Coconut tree, scientifically known as Cocos nucifera, is a tall and graceful plant that can reach heights of up to 100 feet. Its trunk is slender and slightly curved, often swollen at the base, with a smooth, grayish-brown surface.
The tree’s pinnate leaves are long and arching, measuring about 13 to 20 feet long. Each leaf is composed of numerous leaflets, giving the palm its characteristic feathery appearance.
These trees produce clusters of small yellow flowers, which grow at the base of the leaves. The flowers are followed by the development of the familiar fruit: the coconut. These fruits are large and oval-shaped, with a hard outer shell and a fibrous husk. Inside the shell is the edible white flesh and refreshing coconut water.
The appearance of the tree can change with the seasons, particularly in terms of the number of fruits it bears, which can vary throughout the year.
Varieties and Cultivars
Several species, varieties, and cultivars of these palms thrive in different parts of the world, including Hawaii. Some of the most popular varieties include the Dwarf and Tall types.
