The flowers are attached below the leaf and floating in clusters. Each flower has five petals, five sepals, and five stamens. The color is white with yellow centers. The related N. peltata has yellow flowers, and N. indica has feathery fringe on the petal margins. Flowers occur in late summer and early autumn.
