Cup and Saucer Vine is a vigorous and showy vine, native of tropical America, where it grows as a strong woody perennial. The buds start out green and open to reveal the green saucer and bell shaped flowers. The large, pale green flowers become striped with violet, finally changing to deep purple, all on the vine at the same time. Flowers last about 4 days, and have a musky fragrance. This is complemented by violet shaded tendrils and leaves that grows up to 8 cm.
