Name derivation:
Hakea named after Baron Christian Ludwig von Hake (1745-1818), a German horticulturalist and patron of botany. Ednieana named after John Ednie Brown (1848-1899), a Scottish born sylviculturist, conservator of forests in South Australia and author of Forest Flora of South Australia.

Fruit type:
Red brown woody narrow ovoid fruit to 28 mm long, often pubescent. Fruit split into two to reveal two seeds.
Seed type:
Brown ovoid seed to 8 mm long and 5 mm wide (25 mm long and 7 mm wide including the wing that extend narrowly down both sides of seed).

Seed collecting:
Collect mature woody fruit that are 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. 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 viability:
From one collection, the seed viability was average, at 75%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
