Acacia koaia is a tree.
Acacia koaia was described by Wilhelm B. Hillebrand in 1888. The name is considered as validly published.
The comparatively fast-growing and long-lived trees have a rounded habit and reach heights of 4 to 5 metres. The main growing season is all year round.
Wood and Bark
Acacia koaia is evergreen. The dark-green, bipinnate leaves are alternate. The leaflets are ovate and have entire margins. The foliage is dense.
Flowers and Fruits
Acacia koaia produces showy yellow globose flowers from March to April.
All year round the trees produce ornamental, edible yellow legumes that are persistent on the plant.
The trees prefer a sunny situation. They prefer sandy, gritty-sandy, loamy, sandy-loamy or gritty-loamy soil with a pH between 4 and 7,4. The plants need a soil depth of at least 91 centimetres for good growth. They tolerate temperatures down to -40Â°C (USDA zone 3) and need a frost-free period of at least 52 weeks.
