The white flowers of Erica pannosa nod in stem-tip umbels or clusters on long, white peduncles or stalks that are sometimes dull pinkish red near the base. A whorl of remote leafy bracts surrounds the stem-tip where the flower peduncles emerge.
The peduncles and calyx are hairy, the hairs fine and soft, white and somewhat sparse. The base of the calyx is white, the margins of the small (2 mm long) sepals green, conspicuous upon the back end of the corolla.
The corolla is urn-shaped, its short, rounded lobes curving out slightly, not star-like. The corolla is about 4 mm long. The stamens and stigma are (mostly) included in the corolla. Flowering happens from end summer to midwinter (Bond and Goldblatt, 1984; Baker and Oliver, 1967; iSpot).
