The prolific pink-hued flowers are axillary and are borne along the upper short lateral branches. Leaves are 5-10 mm long and obovate with a characteristic Myrtaceae smell when crushed. It can be used for cut flowers as severe pruning has no detrimental effect on its vigour or shape. Pruned well, it will generally flowers more profusely in the second year and its potential for cut flowers is excellent. Like most Thryptomene species, T. saxicola is spring flowering, but carries some flowers most of the year.
Propagation is usually by cuttings as seed has proved to be unreliable.
Tip cuttings, taken in spring and placed on a propagation bench with bottom heat, give best results. Hormone rooting powder used before placing the cuttings on the bench greatly enhances the percentage strike. Under these conditions rooting usually takes four to eight weeks. Cuttings taken in spring should be advanced enough for autumn planting. The site should be well-drained with some frost protection, although only the hardest frost affects this species.
