This fast-growing climber quickly forms an attractive screen of relatively large, distinctly lobed foliage, but it's for the abundance of tubular summer flowers that this plant is most highly prized. Initially these are red, but as they age they turn orange, then yellow, and then finally creamy white. Forming in one-sided sprays that can grow to 30cm in length, there are usually red, orange and yellow blooms at the same time, so they really put on a good display, which lasts for several months throughout summer. It's most often grown as an annual, however it is possible to keep it in a pot and overwinter it where temperatures do not dip below 10C.
