The Erica irregularis flowers grow in small, spaced clusters from leaf axils, mostly on small side-branchlets, forming plume-like racemes up the stems. Their 5 mm long, slender, felted pedicels leave most of them pendulous.
Flower colour is several shades of pink, the shape more or less globular. The flower-coloured, lanceolate to oblong sepals clutch the lower part of the corolla. The keeled tips of the pointed, papery sepals have the darkest colouring on the flowers in picture.
The urn-shaped corollas are about 4 mm long, variably constricted at the mouths. The obtuse corolla lobes are short, rounded and erect, not spreading. The eight, brown, oblong to wedge-shaped anthers are included in the corollas, as is the style and the pin-like stigma.
The ovary, shaped like an inverted green cone, is positioned on a large disc inside the corolla (Manning and Helme, 2024; Privett and Lutzeyer, 2010; Mustart, et al, 1997; Baker and Oliver, 1967; iNaturalist; iSpot).
