It is a large climbing shrub of the Combretaceae family. The young shoots are very downy. The leaves are subopposite, short-petioled, from round-oval to oblong-cordate, entire, villous, their points triangular and acute. The stipules are absent while the spikes are terminal and axillary, villous. he flowers change in colour with age and it is thought that this is a strategy to gather more pollinators.
The flower is initially white and opens at dusk. This attracts hawkmoths with long tongues for pollination. On the second day, it turns pink and on the third, it turns red attracting day flying bees and birds. The flower also changes from a horizontal orientation to a drooping pose.
