The white to deep pink and sometimes fragrant Strumaria truncata flowers each has six narrowly obovate tepals growing in two concentric whorls. The corolla is funnel-shaped, from 8 mm to 10 mm long. The outer three tepals, here visible in the still closed buds, show more floral colouring on their outer surfaces than any other components of the inflorescence. Open flowers are paler, even more so on the insides.
The six pale-anthered stamens are exserted but upside-down as the flowers nod from their pedicels. The filaments cohere with the style nearer the base. They are white and fleshy, tapering markedly to their tips (Manning and Goldblatt, 1997; Bond and Goldblatt, 1984; iNaturalist; JSTOR; https://www.pacificbulbsociety.org; http://pza.sanbi.org; http://www.llifle.com).
