Wattles (Acacia) are among the most vibrant plants in the southern Australian bush, with their iconic yellow blooms particularly visible in late winter and spring. As the largest genus of flowering plant in Australia, they are one of the most resilient, recognisable and culturally significant native plants. However, they can be difficult to identify at a species level. This comprehensive guide to all 121 species and subspecies of wattles found in Victoria and Tasmania includes notes on the habitat, distribution and special properties of each species. Identification keys, high-quality field photos and distribution maps enable easy identification, and fascinating detail on the etymology of species names, their use as food and the taxonomic history of the group is also included. This guide will inform and inspire botanists, conservationists and wattle enthusiasts.
