The small, pink flowers of Erica gracilis grow stalked in small stem-tip clusters, often in profusion from small side-branchlets. There are leaf-like bracts on the flower stalk and four narrow sepals, purplish in colour, at the base of the about urn-shaped corolla.

The dry and faintly hairy corolla has four, shallowly rounded lobes angling out slightly from the widish mouth. The dark anthers are included, the stamens shorter than the style.

Flowering happens from winter to early summer (Bond and Goldblatt, 1984; iNaturalist).
