Acacia cultriformis
Acacia cultriformis is a striking, small evergreen tree or large shrub prized for its unique, triangular, knife-shaped leaves (phyllodes) and profuse, bright yellow, ball-shaped flower clusters. Native to Australia, this fast-growing, drought-tolerant plant features silvery-gray to gray-green, sharply angled foliage that provides excellent textural contrast. In late winter to early spring, it produces an abundance of small, fragrant, golden-yellow flowers in dense, spherical clusters (racemes) that cover the branches, creating a spectacular, colorful display that attracts bees, butterflies, and other pollinators. With its multi-trunked, shrubby form, excellent heat and drought tolerance, and sharp, pointed foliage, it is an outstanding choice for a privacy screen, barrier plant, specimen accent, or as a colorful addition to xeriscape and Mediterranean gardens.
