Eremophila neglecta is a shrub with its branches sticky and shiny due to the presence of resin and which grows to a height of between 1 and 2.5 m (3 and 8 ft).

Flowering occurs mainly from July to September and is followed by fruits which are woody, oval to cone-shaped with a swollen base and a pointed end and are 6–8 mm (0.2–0.3 in) long.

[2][3] The species was first formally described in 1914 by John McConnell Black and the description was published in Transansactions and Proceedings of the Royal Society of South Australia.

[8] Eremophila neglecta leaves contain serrulatanes which have antimicrobial activity against Mycobacterium species and the naphthoquinone biflorin.

It grows in a wide variety of soil types but does best in full sun, is very drought tolerant and is only damaged by the most severe frosts.
