An unusual acacia that is slow growing. Branches tend to grow at odd angles to each other giving the tree it's twisted silhouette. Foliage is dark green, compact and is held very close to the branches allowing the twisted nature of the branches to be apparent. Fragrant in bloom and is a favorite of bees and other pollinators. Blooms in early spring here. Seed pods are small, barely showing through the foliage. This tree is susceptible to termite damage but relatively pest free otherwise. Drought and heat tolerant.
