Grevillea juniperina
Juniper Leaf Grevillea is a small, prickly-leaved shrub from eastern Australia, grown for its spider-like red, orange or yellow flowers that attract birds. Give it good drainage and it adapts easily to many soils.
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 southeastern 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 0.2–3 m (0.66–9.84 ft) high, G. juniperina generally grows 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.
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.
Subspecies allojohnsonii is found on the Northern Tablelands and North West Slopes in northern New South Wales, from Walcha north to Tenterfield and Stanhope and Girraween National Park in southern Queensland.
