Catharanthus roseus
Madagascar Periwinkle
Few bedding plants take Gulf summer heat the way Catharanthus roseus does. The Madagascar Periwinkle is a compact evergreen perennial of 0.3 to 0.6 metres, carrying five-petalled flowers in white, pink, magenta and red almost continuously while the weather stays warm.
It is the standard choice for roundabouts, median strips and mass bedding in hot climates, holding colour on modest irrigation where softer annuals collapse.
