The white to pale pink flowers of Crinum moorei grow at the top of a sturdy, straight scape in groups of five to ten.
The flowers are funnel-shaped, the corolla tubes about 9 cm long. The tepal lobes are erect and widely open at night while drooping by day. The flowers are strongly night-scented, probably courting moths. The tepal lobes become 10 cm long, 4 cm wide. The stamens arch down; the narrow, oblong anthers are black.
There is a robust form of the plant flowering in early summer, while the more common autumn-flowering form has flowers that outlast the leaves (Pooley, 1998; Manning, 2009; Duncan, 2010).
