Lophospermum scandens

About

Lophospermum scandens is a scambling or climbing herbaceous perennial native to south central Mexico, with red-violet and white tubular flowers and toothed heart-shaped leaves. It grows at elevations between 1,400 and 2,400 m in dry habitats, including deciduous oak forests and recent lava flows. The long-tubed flowers are pollinated by hummingbirds. It has been used in gardens as an ornamental plant since the mid-19th century. Its roots require protection from frost in regions where this occurs in the winter. Hybrids of L. scandens are also grown.
