Cootamundra Wattle. 5m high x 5m wide. This is a very fast growing small tree with beautiful grey feathery foliage and bright yellow flowers in Winter. The flowering is sometimes so prolific that it hides the foliage. The species can seed itself so it is best not to plant it near areas of natural bush land to prevent it from establishing feral populations, but in urban areas it makes a magnificent small street tree.
