Eremophila decipiens is a low, sprawling shrub with many tangled branches growing to a height of between 0.3 and 1.0 m (1 and 3 ft).
The ends of the branches and the leaves are sticky and shiny due to the presence of resin.
The leaves are arranged alternately, sometimes densely clustered, sometimes scattered along the stems.
They are glabrous, linear to lance-shaped, sometimes with a few irregular teeth on the margins, mostly 15–46 mm (0.6–2 in) long and 1.5–9 mm (0.06–0.4 in) wide.


The flowers are borne singly in leaf axils on a S-shaped stalk 11–22 mm (0.4–0.9 in) long and at least twice as long as the longest sepal.
There are 5 egg-shaped to triangular, slightly overlapping sepals mostly 3–6 mm (0.1–0.2 in) long which are slightly hairy and sticky.
The petals are 15–30 mm (0.6–1 in) long and joined at their lower end to form a tube.
The petal tube is red, orange or sometimes yellow and lacks spots.
The outer surface of the petal tube and lobes are usually glabrous, often sticky while the inside is covered with short hairs.
The four stamens extend beyond the end of the tube.
Flowering occurs from February to December, although in the Esperance region mostly between July and November.
The fruits are dry, cylinder-shaped to almost spherical, glabrous with a papery covering and are 4–7.5 millimetres (0.2–0.3 in) long.

Eremophila decipiens is sometimes mistaken for Eremophila glabra but the latter species lacks a long, S-shaped flower stalk.
