Mixed Cup and Saucer Vine

5 Seeds

Cup and Saucer Vine is a fast-growing ornamental climbing vine famous for its large bell-shaped flowers surrounded by green calyx "saucers." The flowers usually open greenish-white, then mature into lavender to deep purple, with a pleasant honey-like fragrance. It can climb 4–8 meters, making it perfect for pergolas, trellises, fences, arches, balconies, and walls. In the Gulf, it grows best during the cooler months.
