This plant is known as Tar Bush, or sometimes as Emu Bush. We’re not sure where those common names come from, but can explain the plant’s botanical name – Eremophila glabra. Eremophila is Greek for desert/wilderness lover, which is appropriate, since Tar Bush grows in many dry parts of mainland Australia. Glabra means hairless and refers to the fruit, though some say that it refers to the leaves.
We noticed this Tar Bush growing in the bushland on Buckland Hill in the west of Perth. The flowers are small and almost unnoticeable, but reward closer inspection.
