It produces trumpet-shaped, orange to red flowers up to 3 in (8 cm) long that appear in loose clusters of 6 to 12.

It is a woody, clinging, perennial vine that attaches itself to structures and climbs vigorously with aerial roots like those of ivy.

Like its parents it is hardy but in cooler temperate regions requires the shelter of a sunny wall to produce its spectacular flowers in abundance.
