Syn. Marsdenia floribunda (Brongniart) Schlechter 1899
This climbing plant has long climbing stems with opposite pairs of glossy dark green leaves. Older stems become woody. The fragrant waxy white flowers have a long flower tube ending in a 5-pointed star of spread flower lobes.
Native to Madagascar. Suitable for a frost-free (45 °F) conservatory or greenhouse, although it prefers a warmer 60 °F Winter. Best grown in a large pot with a climbing frame as otherwise it will sprawl everywhere. A cool Winter is said to promote flowering.
