Boronia clavata

Common Name: Bremer Boronia

Description: Boronia clavata, commonly known as Bremer Boronia, is an upright, slender shrub native to the south-west of Western Australia. It typically reaches heights between 0.5 to 1.5 meters, occasionally up to 2.1 meters. The plant features bipinnate leaves composed of three to seven linear to wedge-shaped leaflets, each measuring 10–20 mm in length. From August to October, Bremer Boronia produces pale yellowish-green, four-petalled flowers that are about 8 mm long. These blooms are accompanied by egg-shaped sepals approximately 2–3 mm in length. The stems and sepals are covered with short, soft hairs, adding to the plant's delicate appearance. In its natural habitat, Boronia clavata thrives on floodplains and riverbanks, preferring alluvial sand and loam soils. While it is native to Western Australia, cultivating this species in Melbourne requires well-drained soils and protection from extreme conditions. Providing dappled sunlight and ensuring the soil remains moist but not waterlogged can help mimic its natural environment. Regular pruning after flowering can maintain its shape and promote healthy growth.
