They are very large and have a powdery grey covering. As a species native to relatively dry areas, E.macrocarpa is best suited to cultivation in climates which have a dry summer. It has been grown in sub tropical districts but cannot be regarded as reliable in those areas. It has been observed growing and flowering in western Sydney. The species develops a lignotuber and should respond to hard pruning to near ground level if rejuvenation is required.
Propagation is from seed which germinates readily.
