Eremophila debilis is a prostrate shrub with spreading stems up to 1 m (3 ft) long.
It has glossy green, elliptic to lance-shaped leaves which are mostly 32–85 mm (1–3 in) long, 8–20 mm (0.3–0.8 in) wide and glabrous usually with 3 or 4 pairs of prominent teeth on the edges.

The flowers are borne singly or in groups of up to 3 in leaf axils on a stalk 3.5–7.5 mm (0.1–0.3 in) long.
There are 5 green, lance-shaped, slightly overlapping sepals mostly 7–10 mm (0.3–0.4 in) long.
The petals are 8.5–11 mm (0.3–0.4 in) long and joined at their lower end to form a tube.
The petal tube is white to pale mauve and, unlike many others in the genus, does not have spots.
The petal tube and lobes are mostly glabrous on the outside but the inside of the tube is filled with soft hairs.
The 4 stamens are fully enclosed within the tube.
Flowering mainly occurs in spring and summer and is followed by rounded, fleshy, white to reddish purple fruits, which are 7–10 mm (0.3–0.4 in) in diameter.
