Prickly spider-flower

Grevillea juniperina

''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.
