By setting sample plot, the methods of field investigation and literature review were conducted to analyze and evaluate ornamental plant resources of Nanning acacia garden. The results showed that there were 117 ornamental plants in Nanning acacia garden, which belonged to 102 genera and 57 families. The trees occupied the largest proportion, and vine plants occupied the smallest percentage with only 1.71%. Difference between large section and small section was obvious. Colors of tree species were abundant, and red was the main color, blue and orange were the least. There was no difference between the ratio of tree-shape view trees, leaf view trees and flower view trees, but flower view trees were much more than fruit view trees, and both increased and then decreased with the seasons changed. It was suggested that more species of the vine could be planted in order to built vertical greening landscape and aquatic plants could be actively introduced and planted in order to enrich the diversity of the urban wetland landscape.
