It is an erect, spiky shrub with hairy stems, linear to narrow elliptic leaves with stipules at the base, and yellow-orange and red flowers.

Flowering occurs from October to November and the fruit is a hairy pod, the lower half enclosed with the remains of the sepals.

[2][3][5] Pultenaea juniperina was first formally described in 1805 by Jacques Labillardière in his book Novae Hollandiae Plantarum Specimen.

[8] The common name "prickly bush-pea" is used on the mainland for this species and for the rare Pultenaea aristata.

[19] Prickly bush-pea is endemic to south-eastern Australia where it grows in forest, woodland and heath.
