What does Porcelain flower look like?
Porcelain flower is a climbing perennial with smooth, pale grey stems that can twine around supports. Its leaves are thick, shiny, and shaped like ovals or hearts, measuring up to 13 cm long. The plant produces clusters of star-shaped flowers, usually light pink but sometimes nearly white or dark pink, each about 1.5 to 2 cm across.
