"Grevillea juniperina", commonly known as Juniper Grevillea, is a shrub which is endemic to eastern New South Wales and south-eastern Queensland in Australia.

It has a spreading or erect habit and it grows to between 0.2 and 3 metres in height. The leaves are prickly and are 0.5 to 3.5 cm long and 0.5 to 6 mm wide. Flowering occurs throughout the year, peaking between mid winter and early summer. The spider-like flowers are red, pink, orange, yellow or greenish.

Taxonomy

The type specimen for this species was collected from Port Jackson area and was described by botanist Robert Brown in 1810 who gave it the specific epithet "juniperina" which alludes to its juniper-like foliage.

There are currently seven recognised subspecies:

*"G. juniperina" subsp. "allojohnsonii" Makinson - red flowers
*"G. juniperina" subsp. "amphitricha" - from the Shoalhaven River area
*"G. juniperina" subsp. "fortis" Makinson - mostly within the ACT
*"G. juniperina" R.Br. subsp. "juniperina" - endemic to western Sydney
*"G. juniperina" subsp. "sulphurea" (A.Cunn.) Makinson (formerly var. "trinervata")
*"G. juniperina" subsp. "trinervis" (R.Br.) (formerly "Grevillea trinervis")
*"G. juniperina" subsp. "villosa" Makinson - from the Braidwood / Currockbilly area.

"G. juniperina" subsp. "juniperina" is listed as a vulnerable species on Schedule 2 of the Threatened Species Conservation Act 1995 in New South Wales.
