The five-petalled flowers appear in late spring and summer, but it is not unusual to see the odd flower throughout the year. Each bloom is held on a slender, long stalk above the leaves and is about 1.2 cm in diameter. They are fragile and unsuitable for picking as is the entire genus, but the profusion of flowers makes it a most suitable garden plant. In cultivation, H. pedunculata will tolerate all but very wet conditions, but its habit lends itself to rock garden culture and it thrives in the well-drained soils of a rockery. Plants in the Australian National Botanic Gardens have shown no damage by frost.
Propagation is easy from cuttings taken when new growth has begun to harden off.
Such material can be found from late spring to autumn in well-grown plants. It may also be possible to obtain new plants by layering, making use of the species' habit of rooting at the nodes. The growth habit of H. pedunculata is very compact and it tends to suppress weed growth when used as a ground cover planted at 50 cm centres. Look here for a glossary of botanical terms.
