Maurandya scandens
Maurandya scandens is a climbing herbaceous perennial native to Mexico, with pink and white tubular flowers and untoothed leaves. It is grown as an ornamental plant in many parts of the world, and has commonly escaped from cultivation to become naturalized. It has been confused with "Lophospermum scandens", which has longer flowers and larger, toothed leaves. It resembles "Maurandya barclayana", which has blue-violet flowers and hairy rather than hairless sepals.
