Also known as Narrow-Leaf Gimlet, Swamp Mallee is potentially one of the best small eucalyptus for desert residential landscapes as it is highly tolerable of poor soils and harsher conditions. A tough and rugged species, it tolerates cold, heat, wind, smog, aridity, saline and alkaline soils, and sea coast exposure, and is extremely drought tolerant although occasional summer irrigation is beneficial in hot areas.
