Whilst it is very similar to Common Gorse (Ulex europaeus), Ulex gallii tends to be smaller and low-growing, with narrower and weaker thorns and stems, forming compact, lighter green mounds. It also flowers later (July to September) whilst Common Gorse (Ulex europaeus) flowers mainly in spring.

The bracteoles are less than twice as wide as the pedicels, and the thorns are moderately grooved.
