Marsdenia oreophila (syn. Cionura)

An unusual and exotic looking evergreen climber bearing clusters of starry, deliciously spicy-sweet scented, creamy-white flowers over a long period in summer. Reaches about 5m on a sunny wall in well drained soil and will be best grown with such shelter. Has survived for years on a house wall in a customers cold Midlands garden and another chap has it up to the rafters in Bristol, even through Dec 2010.
