Plant description

Bushy to slender tree to 5 m high, re-sprouting from the base; bark dark and fissured; young leaves, branchlets and inflorescences with ash-white hairs. Leaves compound, to 95 mm long, terete, sometimes obscurely grooved below; divided many times with a pungent tip; grey-green with white hairs. Inflorescence a spike with 35-105 yellow flowers. Flowering between May and November. Fruits are greyish-brown woody narrow ovoid fruit to 42 mm long and 12 mm wide, with a sharp pointed end. Fruit splits into two to reveal two seeds. Seed embryo type is investing.

Seed collection and propagation

Collect seeds between October and January. Collect mature woody fruit that are greyish-brown and not split. These will contain seeds. 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. Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
