[3] The pink trumpet vine grows as an evergreen, vining shrub with woody and twining stems, lacking tendrils, that can reach a height of 5 m. The up to 25 cm long, opposite leaves are imparipinnate and composed of 5 to 13 ovate, lanceolate-ovate to broadly oblong-elliptic, pointed leaflets, 2-7 x 1-3 cm or somewhat larger on new shoots.

The leaves are dark green, with a somewhat toothed margin, a cuneate base, often somewhat asymmetrical, and a short to long acuminate apex.

The pink flowers have reddish stripes in the center, veined darker in the throat, are in terminal panicles, are bell-shaped, five-lobed (while slightly two-lipped), fragrant and reach a size of up to 7.5 × 7.5 cm.

The corolla is 6-8 inches tall and wide with a spreading five-slip hem and is pale pink to yellow-white, with pinkish-red stripes and spots on the inside and widens bell-shaped from the narrow base.

[4] The fruits are up to 40 cm long, cylindrical capsules that open bivalvely at maturity, releasing numerous winged seeds.
