The Australian shrub of rigid needles that has turned whole central sierras into impassable walls. After a fire it opens all its capsules at once and seeds the ground with thousands.

Where it grows

Scrubland · Uplands · Pine woods

Also known as

needlebush, bushy needlewood

In flower

How to tell it

Rigid needle leaves with a sharp tip that genuinely stab. Hard grey woody capsules clinging to old branches, with a curved beak. Small white flowers in winter.

What it is confused with

No dangerous lookalikes known in the Iberian Peninsula.

What it is for

None. It was planted as hedge and windbreak, and is today one of the costliest invaders to fight in Portugal. Where hakea grows, scrub stops being crossable and fire gets worse.

The law says

An invasive alien species in Portugal, with control plans in several sierras. Do not plant or propagate it.
