Eremophila is a genus of 214 species which are commonly called "emu bushes". The plants produce fleshy fruits which are often eaten by birds and animals. The plants are also known as "poverty bushes" because of the ability of many of them to survive in very dry, inhospitable environments. Those species which occur in the harshest of climates have developed methods to cope with the severe conditions. Many have greyish, hairy foliage which reflect the sun's rays while other have a shiny, sticky coating on the foliage as a protection against drying winds. Most emu bushes are propagated by cuttings or other vegetative means (such as grafting) as the seed can be difficult to germinate reliably.
