Dillwynia sieberi, commonly known as Sieber's parrot-pea,[2] is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia.

It is an erect shrub with rigid, needle-shaped, sharply-pointed leaves and yellow to yellow-orange flowers with reddish-brown markings.

Flowering occurs from April to November and the fruit is an oval pod 5–6 mm (0.20–0.24 in) long with the remains of the petals attached.

[2][3] Dillwynia sieberi was first formally described in 1840 by Ernst Gottlieb von Steudel in his book Nomenclator Botanicus.

[6] Sieber's parrot-pea grows in forest and woodland and is widespread along the ranges and western slopes of New South Wales and the Australian Capital Territory, and in coastal areas between Newcastle and Nowra.
