Lobelia coronopifolia is a tufted, soft shrublet reaching heights around 30 cm. The spreading stems branching from the base are soft, whitish and hairy.
The toothed or lobed leaves are narrow to lance-shaped, hairy in picture on their lower parts or winged stalks. The largest lobes are near the leaf centre, curving up on the plant in picture, the leaves folding in slightly at their midribs. Leaf dimensions are up to 4 cm by 5 mm.
The specific name, coronopifolia, is derived from the Greek corona (crown), ops (ability) and folium (leaf), relating to the crown-like leaf margins.
