Acacia is a genus of flowering plants in the family Fabaceae, commonly known as the legume, pea, or bean family. It includes over 1,300 species, many of which are native to Australia and Africa. Acacia trees and shrubs are characterized by their feathery leaves and bright yellow or white flowers, which often grow in clusters. These plants are important for their ecological roles, providing habitat and food for various wildlife. Some species, like Acacia senegal, are known for producing gum arabic, a substance used in food and industrial applications. Acacias are also used in landscaping and erosion control due to their hardiness.
