Olearia axillaris

Olearia axillaris, or Coast Daisy-Bush, is a densely branching shrub in the family Asteraceae, native to coastal regions of Australia. Known for its resilience to salt spray and harsh coastal conditions, this hardy species thrives in sandy, well-drained soils and full sun, making it a staple in coastal ecosystems. It typically grows into a compact form, providing structural stability and habitat in dune and coastal landscapes.

The narrow, aromatic leaves of Olearia axillaris are up to 25 mm long, with rolled-under edges. The adaxial (upper) surface of the leaves is hairless and grey-green, while the abaxial (lower) surface is woolly white, creating a striking two-tone effect when viewed from below. From February to April, the plant produces small flowers in the leaf axils, adding subtle charm and seasonal interest to its natural surroundings.

This species is well-adapted to withstand strong winds, salt spray, and nutrient-poor soils, making it a valuable plant for coastal revegetation, dune stabilization, and biodiversity-focused projects. Its dense branching habit provides shelter for small animals and nesting sites for coastal birds, contributing to the ecological health of its habitat.

With its aromatic foliage, distinctive appearance, and ability to thrive in challenging environments, Olearia axillaris is an excellent choice for sustainable coastal landscaping, habitat restoration, and erosion control. Its combination of toughness and aesthetic appeal makes it a standout species in the preservation and enhancement of coastal ecosystems.
