River wattle (Acacia cognata) in a medium form presents as a moderately sized woody perennial with arching stems and fine-textured foliage. The phyllodes are slender and arranged closely along the branches, forming a soft, continuous canopy. The plant retains its characteristic flowing structure while maintaining a more contained branching system.

Native to southeastern Australia, Acacia cognata inhabits riverine environments and open woodlands where it adapts to varying moisture conditions. The species is biologically notable for its nitrogen-fixing ability and resilience to environmental stress. In this medium form, the plant emphasizes balanced growth, maintaining its flowing habit and dense foliage while presenting a more restrained structure compared to larger expressions.
