Eremophila glabra, also known as tar bush, is an evergreen shrub native to Australia. It can grow from 10 to 300 cm tall, and can be either prostrate or erect in form. The leaves are variable in size and shape, and lance-shaped, linear or egg-shaped. The flowers are usually red, orange, yellow or yellowish green, and don't have spots. It grows well in most soils and in most positions from full sun to full shade. It is drought-tolerant and frost-tolerant, though a few forms with hairy leaves will not tolerate high humidity. Tar bush is a popular choice in native gardens, and a number of cultivars have been developed. Propagation from seed is difficult, but cuttings strike readily and preserve the features of the parent plant.
