Hakea petiolaris (Sea Urchin Hakea) - A fast growing upright evergreen shrub or small tree to 10 to 18 feet tall with reddish stems holding Eucalyptus-like 2 to 4 inch long by 1 to 2 inch wide broadly obovate leathery pale gray-green leaves. In fall through early spring appear the spherical clusters of many (120 to 200) small pink and cream colored flowers that are held on the stem branches or in their forks and followed by interesting tight clusters of small irregularly shaped woody fruit. Plant in full sun in a well drained soil and irrigate occasionally to infrequently. Once established this plant is quite drought tolerant and it tolerates coastal conditions and most any soil type so long as it drains well. Cold hardy without damage to around 25 F and able to survive with tip damage temperatures down to around 18 F. Prune young plants to make fuller. A tough and showy plant for use as a specimen, as a screening or windbreak planting, an informal hedge or trimmed up as a small tree. Its flowers are attractive to nectar feeding birds and are also nice in floral arrangements. Hakea petiolaris comes from the mediterranean climate region of south west Western Australia. The name for the genus honors Baron Christian Ludwig von Hake, a 18th and 19th century German patron of botany. The specific epithet is derived from the Latin word 'petiolus' meaning a "small, slender stalk", in reference to the long conspicuous leaf petiole. We thank Jo O'Connell at Australian Native Plant Nursery for supplying us with this attractive Australian plant.  The information displayed on this page is based on research conducted about this plant in our library and from reliable online sources. We also consider observations that we have made of it growing in the nursery's garden and in other gardens, as well how it has performed in our crops out in the nursery field. We will incorporate comments that we receive from others as well, and welcome hear from anyone who may have additional information, particularly if they have knowledge of cultural information we do not mention that would aid others in growing Hakea petiolaris.
