Bossiaea walkeri is a rigid, much-branched shrub that grows up to 2 m (6 ft 7 in) high and wide and is more or less glabrous.

[2][4][5][6][7][8] Bossiaea walkeri was first formally described in 1861 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected by Alexander Walker on hills between the Lachlan and Murrumbidgee Rivers.

[2][4][5][6][7] The species is rare in Victoria, where it is listed as "endangered" under the Victorian Government Flora and Fauna Guarantee Act 1988.

It can be grown in full sun or part shade, is drought and frost tolerant but needs relatively dry, well-drained soil.
