Notes
Pincushion hakea (Hakea laurina) is regarded as an environmental weed in Victoria and South Australia. This species has escaped cultivation in south-eastern Australia and tends to rapidly invade natural habitats adjacent to where it is planted. It is especially aggressive in coastal situations and regenerates prolifically after burning. Its seeds are also stimulated to germinate by heat, and seedlings can be found in very high numbers after fires. Infestations of this species eventually smother indigenous vegetation and prevent the regeneration of locally native species.
Pincushion hakea (Hakea laurina) is a popular garden shrub in south-eastern South Australia. It is also listed as a common environmental weed of the Adelaide region and is also a known environmental weed in the nearby Mount Lofty Ranges. An infestation was present in Ferguson Conservation Park, in suburban Adelaide, but it is thought to have been eradicated. Pincushion hakea (Hakea laurina) is also naturalised in the Gippsland Plain Bioregion and present on numerous local environmental weed lists in southern Victoria (e.g. in Knox City, Frankston City, City of Hume, Surf Coast Shire and the Geelong Region).
