Allamanda cathartica
Golden Trumpet Vine
Bright yellow trumpets carried against glossy whorled foliage are the signature of Allamanda cathartica, the Golden Trumpet Vine. It is a scrambling evergreen climber from tropical South America that flowers through most of the warm season and rarely stops entirely where the climate stays frost-free.
It is trained over pergolas, arches and boundary walls, and can equally be kept clipped as a loose flowering shrub in mass planting.
