There are 3 common Acacia trees in Hong Kong. They are all exotic species. Since they are easy to cultivate and grow very fast, they have been extensively planted in country parks and in city gardens. In order to distinguish the 3 Acacia trees, the easiest way is to compare their leaf size. The one has largest and broadest leaves is the Big-leaved Acacia (Acacia mangium); the one has smallest and narrowest leaves is the Taiwan Acacia (Acacia confusa); with leaf size in between is the Ear-leaved Acacia (Acacia auriculiformis). Their flowers and fruit pods are also different from each other. Do you know how to distinguish them?
