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.

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.

Varieties

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.

A number of cultivars have been selected for horticultural use, including the following:

  • 'Lunar Light' - variegated leaves and orange-pink flowers
  • 'Molonglo' is a form with a low spreading habit and larger orange flowers with red styles. It was bred from two disparate forms of juniperina, an erect red-flowered form from around Canberra and a yellow-flowered spreading prostrate form from the western slopes of the Budawang Ranges in 1964.[1]
