About
Frankenia pauciflora, the common sea-heath or southern sea-heath, is an evergreen shrub native to southern Australia. It is part of the Frankenia genus of the Frankeniaceae family.
It can be prostrate or may grow up to 0.5 m in height. Pink or white flowers are produced between June and February in its native range. It occurs in saline flats, salt marshes, or coastal limestone areas.
Where it grows
Frankenia pauciflora is characterized as a halophyte and as such is found to localize in sandy soils, salt floats, salt marshes, and coastal limestones. The plant subsists in environments with a soil class of S2 and S3 which is described as moderately to highly saline soil. The species is a xerophyte, a drought-tolerant plant and survives in environments with sustained predictable dry periods followed by periods of moist soil. Frankenia pauciflora can subsist in a range of soil pHs ranging from acidic to alkaline. In addition, the plant tolerates hot overhead sun to warm low sun and is characterized as is shade tolerant.
Uses
The relative simplicity of growth and ability for the plant to adapt to a wide range of soils makes Frankenia Pauciflora an attractive choice for home gardening. Its flame-retardant properties also provide reduced chances of bush-fire spread in risk zones such as Australia when planted surrounding homes.
