This species is very variable with a wide range of flower colours from white, cream, yellow, pink, red or brown, all with purplish blotches or stripes inside the flower bell.
Generally it adapts well to cultivation in a range of soils and responds well to pruning, which may be needed to keep it under control. It is very vigorous and can quickly climb into the highest trees. When this occurs, its presence will only be noticed by the masses of flowers in the treetops.
