Acacia farnesiana, also known as Mealy Wattle, Needle Bush, or Sweet Acacia, is celebrated for its intoxicatingly fragrant blooms. This beautiful, semi-evergreen shrub or small tree features a naturally spreading, vase-like form with zig-zag stems that are adorned with sharp thorns. Its finely divided, feathery leaflets boast a soft green hue, adding an elegant touch to gardens year-round, provided the soil retains moisture in warmer regions. In late winter to early spring, clusters of small, bright golden-yellow puff-like flowers burst into bloom, offering a long-lasting display of color and scent.
Beyond their ornamental appeal, Sweet Acacia's flowers are cherished for extracting cassie perfume, a favorite in Southern European gardens since the 1600s. The tree, reaching heights and widths of 15-20 ft., is highly drought-tolerant and pest-resistant, making it a low-maintenance choice for landscapes. While ideal for barrier plantings, thanks to its sharp thorns, it's also favored by wildlife as a nesting haven.
Thriving in full sun or part shade and well-drained soils, Sweet Acacia is salt and drought tolerant once established, though it favors full sun for optimal flowering. Despite its resilience, it's important to avoid heavy, clay, or wet soils. Notably resistant to deer, it can be propagated through scarified seeds but requires careful placement away from high-traffic areas due to its spines. Pruning helps maintain its structure, and it's generally trouble-free, though vigilance against pests like caterpillars and root rot is advised. Native from southern California to Florida and stretching into Central and South America, Sweet Acacia continues to enchant with its aromatic blooms and striking presence.
