The sweet-scented flowers of Crinum paludosum each has the usual six tepals in two whorls that characterise lily flowers. The flowers are nearly erect or nodding.
The perianth tubes are slender. The tepals are lance-shaped and white, or (less common), shades of pink with the median keels a deeper pink. Only the tepal tips recurve somewhat, the lower parts are about straight. The tepal dimensions are 8 cm to 10 cm long and 1,3 cm to 3 cm wide.
The showy, bell-shaped corollas often open around noon. They do not last long, only for about two days each (Duncan, et al, 2016; Pooley, 1998; iNaturalist).
