Allamanda blanchetii is a vigorous and handsome climber or shrub with lance shaped leathery leaves and beautiful, deep pink to purplish, trumpet shaped flowers that are produced throughout summer.
Its thick foliage makes a good screen as it is an evergreen.
It does not like dry, hot winds which will make the foliage dry out and scorch.
It does however prefer warmer, moist climates and goes well draped across walls and fences.
