Cionura oreophila

Cionura orephila is a rare evergreen climber of the milkweed family, like the other milkweeds it has scented flowers (Waxy white)  although to my nose this is both the strongest and sweetest scent of the group. Not fully hardy but worth trying on sunny sheltered walls or in the conservatory where its scent is even more strongly noticed. At present I can find no information on the origins of this species which should not be confused with Cionura erecta a deciduous climber from the Mediterranean region
