The species is highly variable, possibly a result of spontaneous mutation, natural hybridization, and autopolyploidy. The flowers bloom all throughout the year and are produced in clusters of 3 to 12 together at the ends of branches. They are strongly scented, with a white corolla 2 to 3 cm (0.79 to 1.18 in) in diameter with 5 to 9 lobes.
