The stem-tip inflorescence of Searsia incisa var. effusa is a branched panicle of up to 5 cm long, hanging from a short spur-branchlet. There is a covering of grey, woolly hairs on the pedicels and calyces.
Flowering happens from winter to early summer.
The plant serves as larval food for a butterfly, Phasis thero, commonly the silver arrowhead or hooked copper that flies about in parts of South Africa during spring (Le Roux, et al, 2005; Coates Palgrave, 2002; Van Wyk and Van Wyk, 1997; iNaturalist).
