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 pedicels emerge.
The pedicels and calyx are hairy, the white hairs of two kinds, viz. some glandular, others felted. There are solitary scale-like or spoon-shaped, stalked bracteoles behind the calyces, covered in sticky hairs. The base of the calyx is white, the tips of the small (2 mm long) sepals green, conspicuous upon the back end of the corolla. The calyces also have both felted hairs and whisker-like gland-tipped ones.
The corolla is urn-shaped, its short, rounded lobes curving out slightly, not star-like. The corolla is about 5 mm long. There are velvety or felted, backward-facing hairs on the corollas that start off white but turn brown soon.
The eight stamens have anthers crested at the base. The anthers and the pinhead stigma are (mostly) included in the corolla, or the latter may just protrude.
Flowering happens from late summer to after midwinter (Manning and Helme, 2024; Bond and Goldblatt, 1984; Baker and Oliver, 1967; iNaturalist; iSpot).
