14 Types of Grevillea Plants (spider flowers)

Grevillea plants, commonly known as spider flowers or Grevillea, are a genus of about 360 species of evergreen flowering plants in the family Proteaceae. These plants are native to Australia, New Guinea, New Caledonia, and Sulawesi.

Grevillea plants are range from ground covers to trees, and have adapted to growing from desert to high mountain zones. Most species are woody shrubs with fine needles or intricately dissected sturdy leaves. The genus was named by botanist Charles Francis Greville in the late 18th century, and they are often planted to attract pollinators like birds and bees.

Characteristics Grevillea Plants

  • They are evergreen shrubs or trees with spider-like flowers and needle-like leaves.
  • The flowers are zygomorphic, arranged in racemes at the ends of branchlets, and are often referred to as “spider flowers”
  • The fruit is a follicle that splits down one side only, releasing one or two seeds.
  • They can grow from desert to high mountain zones, and most species prefer full sun (at least 8 hours of direct sun per day) with well-drained soil.
  • Some species have dense growth habits and can be used as privacy screens, while others with a more open structure can be used as specimen plants or ground covers.
  • The foliage can range from bright lime-green to soft gray to blue-green.
  • Many species of Grevillea are attractive to birds and insects, especially birds like honeyeaters, which feed on the nectar of the flowers.
  • Grevillea plants are deer-resistant and fuss-free choices for warm temperate gardens that mimic their native Australian climate.
  • The genus was first formally described in 1809 by Joseph Knight, and the name was corrected to Grevillea by Robert Brown in 1810.
  • The International Union for Conservation of Nature currently has 314 species of Grevillea on the IUCN Red List, with more than 35% being in a threatened category (Critically Endangered, Endangered or Vulnerable).
