Common Names: Sweet Acacia, Huisache

Native to: Southern United States, Mexico, Central America, and the Caribbean (Texas)

Lighting Requirements: Full sun

Height: 15–25 feet 

Width: 15–20 feet 

Winter Look: Semi-evergreen to deciduous; slender, thorny branches may remain bare in colder climates

Seasonal Interest: Fragrant yellow-gold puffball flowers in late winter to spring; attractive seed pods

Drought Tolerance: High

Soil Requirements: Well-drained soils; tolerates sandy, loamy, or rocky soil

pH Range: 6.0–8.0 (slightly acidic to moderately alkaline)

Hardiness Zones: USDA Zones 9–11

Deer Resistance: High; thorny branches deter browsing

Attracts: Pollinators (bees, butterflies), birds, and small mammals (use seed pods as food)

Potential Issues: Can spread aggressively in favorable conditions; thorny branches can be hazardous in high-traffic areas

Notes: Sweet Acacia is prized for its fragrant blooms and drought tolerance, making it an excellent choice for xeriscaping and wildlife gardens. Minimal pruning is needed to shape or remove dead wood. Its thorns and spreading habit make it better suited for naturalized or low-maintenance landscapes.
