Acacia cultriformis
- Acacia cultriformis, commonly known as Knife Leaf Acacia, is a unique and eye catching shrub valued for its silvery blue foliage and bright seasonal blooms. The small, triangular leaves have a distinctive shape and soft color that give the plant a cool, almost shimmering look in the landscape.
- In late winter to early spring, it produces clusters of small, golden yellow, ball shaped flowers that cover the plant and create a vibrant contrast against the blue gray foliage. The blooms are lightly fragrant and bring a welcome burst of color during a time of year when many plants are still quiet.
- This acacia has a naturally dense, slightly rounded growth habit and works well as an accent plant, informal hedge, or part of a mixed drought tolerant planting. Its color pairs especially well with darker greens and other silver toned plants.
- Acacia cultriformis performs best in full sun and prefers well drained soil. It is highly drought tolerant once established and thrives in Mediterranean and low water landscapes. Like many acacias, it does not like heavy soils or overly wet conditions, so good drainage is important.
- It typically grows 6 to 10 feet tall and wide, forming a full, somewhat open shrub over time. It is well suited for USDA zones 9 through 11 and is hardy down to about 20 to 25 degrees Fahrenheit. The foliage is evergreen, providing year round structure and color.
- This plant is generally considered mildly toxic if ingested, so it is best to use some caution around pets and livestock.
- The flowers attract pollinators such as bees, adding activity to the garden during its bloom season.
- It is moderately deer resistant and typically avoided by rabbits once established.
- With its striking foliage, bright winter blooms, and low water needs, Knife Leaf Acacia is a great choice for adding color and texture to drought tolerant landscapes.
