The small to medium-sized flowers of Erica labialis grow in whorls of four to nine, clustered into heads that nod from the tips of side-branchlets. The flowers have various shades of pink. There are usually no bracteoles. The calyces are tiny, the sepals of lower flowers in each head joined in a two-lobed calyx, while upper flowers have tubular, four-toothed calyces.
The hairless corollas are tubular to funnel-shaped, ending in two shallow, angled to rounded lobes, often with ciliate margins. The specific name, labia, is a Latin word meaning lips, referring to these lobes.
There are four stamens, their blackish maroon anthers oblong and exserted. The ovary is two-chambered. The long, white styles are exserted about double as far as the anthers, the stigmas slightly thickened.
Blooming happens throughout the year (Manning and Helme, 2024; Manning, 2007; Bond and Goldblatt, 1984; iNaturalist; JSTOR; https://www.fernkloof.org.za).
