The flowers of Pelargonium crispum grow in small clusters of up to three on short stalks from leaf axils. They are pink or white with pink, rectangular line markings near the base of the upper pair of larger petals. The smaller, lower three petals are oblong with rounded tips and unmarked. Pink anthers and style with dark pink, branched stigmas are displayed in the flowers in picture. The floral tube is about 8 mm long.
Flowering may occur from late winter to the following autumn, peaking in spring (Vlok and Schutte-Vlok, 2010; Manning, 2009; Bond and Goldblatt, 1984).
