The white, pink or purple flowers of Gibbaeum heathii become from 1 cm to 3 cm in diameter. The species presents the same colour range in its flowers as does the entire genus.
Each flower grows solitary upon a stalk. There are six sepals. The diaphanous petals, here white but not quite, are oblong, rising and spreading around the small flower centre. Each flower centre consists of a few styles and many stamens.
About eight triangular valves can be counted on top of the locules where the seeds had grown in the photo. There are valve wings present, but no covering membranes or closing bodies in this genus.
Flowering happens from late winter through spring (Vlok and Schutte-Vlok, 2010; Smith, et al, 1998).
