Acacia Cognata ‘Limelight’ is a compact Australian native shrub prized for its soft, cascading lime-green foliage and graceful, weeping habit. Its fine-textured foliage provides vibrant year-round colour and creates beautiful movement in the garden, making it an attractive feature for garden beds, borders, courtyards and contemporary landscapes.
Low maintenance and versatile, ‘Limelight’ is an excellent choice for gardeners seeking an attractive evergreen plant that delivers lasting visual impact without taking up too much space. It performs well as a feature plant, mass planting or contrasting foliage plant and responds well to light pruning, allowing it to maintain a neat, dense and attractive form throughout the year.
