Naming

''Hakea sericea'' was first formally described by Heinrich Adolph Schrader and Johann Christoph Wendland in 1797 and published the description in ''Sertum Hannoveranum''. The genus ''Hakea'' is named after Baron von Hake, patron of botany in the 18th century. ''Sericea'' meaning silky, referring to the tiny hairs on young growth.

Distribution

Silky hakea is found from the coast and adjacent ranges of south-eastern Queensland to south-eastern New South Wales. A frost tolerant species, grows in well-drained soil and full sun. A good habitat plant due to its prickly habit and winter flowering.

''H. sericea'' is an invasive weed in some areas outside Australia, specifically in South Africa, New Zealand and Portugal.
