Hakea petiolaris – Sea Urchin Hakea

A large shrub to small tree reaching 2-9 metres in height. Flowers are from late autumn through to early winter and occur in globular clusters, resembling sea urchins. The flowers start creamy coloured, as they age, the perianth darkens and the styles remain cream, creating a lovely contrast. These are followed by large woody pods.  Likes a well drained acid soil, sunny position. Resents too much humidity, which can make them susceptible to root rot. Tolerates moderate frost.

Once you have found the plant that you want, the next step is to find where to get it. Nurseries stock a good range of plants, but due to space and supplies, they may or may not have the wanted plant in stock. If they don’t, they may be able to order it in for you.  Specialist nurseries are also able to give great advice, and if they don’t have the plant you want, they can often suggest alternative plants that will be just as good for you.
