A botanical garden, also known as a botanic garden, is a garden dedicated to the collection, cultivation, preservation, and display of a wide range of plants, labeled with their botanical names, for scientific research, conservation, education, and public enjoyment.

Botanical gardens serve several important functions:

Specialized Collections: Such as cacti and succulent plants, herb gardens, or plants from specific regions.
