Hakea named after Baron Christian Ludwig von Hake (1745-1818), a German horticulturalist and patron of botany. Rostrata from the Latin 'rostratus' meaning beaked or curved; referring to the pronounced recurvature of the beak of the fruit.

Native. Common in South Australia. Common in Victoria.
Plant description:
Spreading or rounded shrub to 5 m tall with white hairs on branchlets and young leaves. Leaves terete, to 150 mm long and 1.7 mm wide, ascending, pungent tip, glaucous. Inflorescence axillary clusters with 1–10 white flowers. Flowering between July and November.
Fruit type:
Greyish-brown woody S-shaped fruit to  45 mm long and 32 mm wide, coarsely wrinkled with a long narrow beak. Fruit split into two to reveal two seeds.
Seed type:
Dark brown to black ovoid seed to 8 mm long and 6 mm wide (17 mm long and 8 mm wide including the wing that extend half way down one end sides of seed).
Embryo type:
Investing.
Seed collecting:
Collect mature woody fruit that are greyish-brown and not split. These will contain seeds.
Seed cleaning:
Place the woody fruit in a tray and leave to dry until it split open. Fruits can be placed in the oven at low temperatures to achieve the same result. Place the dried fruit in a bucket and shake to dislodge the seeds from the valves. Separate the seeds from the fruit and store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
