context_page_description: Grevillea juniperina, commonly known as juniper- or juniper-leaf grevillea or prickly spider-flower, is a plant of the family Proteaceae native to eastern New South Wales and south-eastern Queensland in Australia. Scottish botanist Robert Brown described the species in 1810, and seven subspecies are recognised. One subspecies, G. j. juniperina, is restricted to Western Sydney and environs and is threatened by loss of habitat and housing development.
  A small prickly leaved shrub between 0.2 and 3 m high, G. juniperina grows generally on clay-based or alluvial soils in eucalypt woodland. The flower heads, known as inflorescences, appear from winter to early summer and are red, orange or yellow. Birds visit and pollinate the flowers. Grevillea juniperina plants are killed by bushfire, regenerating afterwards from seed. Grevillea juniperina adapts readily to cultivation and has been important in horticulture as it is the parent of many popular garden hybrids.
context_section_description: Allan Cunningham sent seed of G. juniperina to England in 1820; it was grown there the following year. Baron Charles von Hügel grew the species in Vienna in 1831. It has been grown outdoors in southern England, particularly G. juniperina subspecies sulphurea. Grevillea juniperina adapts easily to cultivation and grows in a wide range of soils and aspects in locations with good drainage. Long-flowering, it attracts birds such as honeyeaters with its nectar. The prickly dense foliage is also a good nesting site and shelter, particularly for smaller birds, such as finches. Many forms and hybrids have been commercially propagated and sold, some having more horticultural appeal than others. Low winter temperatures promote more prolific flowering and pruning promotes dense foliage. Plants are readily propagated by cuttings or seed, although propagation by cuttings is required to ensure the new plants have the same characteristics of the parent. Direct contact with the plant may cause a skin rash.
  Many cultivars have been selected for horticultural use, either selected forms or hybrids with other Grevillea species. One prominent early breeder was Leo Hodge of W Tree, Victoria. Hodge became interested in breeding grevilleas after finding seedlings in his garden. His first trials involved crossing G. juniperina with G. victoriae, producing G. 'Poorinda Queen', which was the first to flower, followed by G. 'Poorinda Constance', G. 'Poorinda Leane' and G. 'Poorinda Pink Coral' respectively, all in 1952.
  Cultivars include:
  'Allyn Radiance' – derived from a prostrate orange and prostrate red forms of G. juniperina.
  'Audrey' – G. juniperina crossed with G. victoriae. Bred in 1957 by George Althofer, who named it after his wife. It grows to 2 m (7 ft) high and wide and produces orange-red flowers over many months. It is popular in South Africa and the USA.
  'Canberra Gem' – G. juniperina crossed with G. rosmarinifolia. Registered with the Australian Cultivar Registration Authority in 1976.
  'Canterbury Gold' – prostrate yellow form of G. juniperina crossed with Grevillea parvula.
  'Goldfever' – G. juniperina crossed with Grevillea rhyolitica.
  'H22' (Gold Cluster) – a dense growing prostrate selection with yellow flowers.
  'Lunar Light' – a low-growing form with variegated leaves and orange-pink flowers. It is suitable for rockeries.
  'Molonglo' – a form with a low–spreading habit and larger orange flowers with red styles. It was bred by Rudolph Willing of Australian National University in 1964, 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 Range in 1964. It is named after the Molonglo River.
  'New Blood' – a compact red-flowered shrub resulting from a cross of 'Molonglo' cultivar with G. rhyolitica.
  'Old Gold' – a low spreading shrub with yellow new growth, lobed leaves and greyish-yellow flowers with pink styles. It is derived from G. juniperina crossed with Grevillea ilicifolia.
  'Orange Box' – G. juniperina crossed with G. victoriae.
  'Pink Lady' – G. juniperina crossed with G. rosmarinifolia. Bred by Stan Kirby of Queanbeyan, it was grown widely in the early 1970s. A shrub to 60 cm (2 ft) high and 3 m (10 ft) wide with pale pink flowers.
  'Poorinda Adorning' – a seedling that grew in Hodge's garden, registered in 1978. The original plant grew in 1965.
  'Poorinda Annette' – a cross with the small-flowered form of Grevillea alpina.
  'Poorinda Beauty' – a cross with Grevillea alpina.
  'Poorinda Belinda' – a cross with a hybrid of the yellow flower form of Grevillea obtusiflora and Grevillea alpina.
  'Poorinda Constance' – a cross with Grevillea victoriae.
  'Poorinda Jeanie' – a red-flowering shrub that grows up to 2 m (7 ft) high. It is derived from a cross with Grevillea alpina.
  'Poorinda Leane' – a cross with G. victoriae. It is a spreading shrub to 4 m (13 ft) high with buff or apricot flowers.
  'Poorinda Pink Coral' – a cross with G. victoriae, named for the colour of its flowers.
  'Poorinda Queen' – derived from a cros
