Bougainvillea is a genus of 18 flowering plants, native to South America, and in the Nyctaginaceae (four-o’clock) family. They are woody vines with a scrambling habit.
Plant them in full sun in sandy or loamy acidic soils with good drainage. They are tolerant of drought, heat, and salt. Traditionally planted along trellises and fences, they can be trained to grow more shrub-like in containers.
