Bougainvillea (Bougainvillea glabra) in a large bush form develops as a sprawling woody perennial with numerous arching and interwoven stems that create a broad, irregular canopy. The branches are slender and often thorny, supporting small, oval leaves arranged alternately along the stems. The plant is best known for its vivid bracts, which surround small, inconspicuous flowers and create bright, papery clusters across the canopy.

Native to South America, particularly Brazil, Bougainvillea glabra thrives in tropical and subtropical climates where sunlight is abundant. A defining biological trait is its climbing tendency, though in bush form it spreads outward without reliance on vertical support. The plant’s thorny stems provide structural defense, while its bracts attract pollinators. In this large bush expression, Bougainvillea glabra emphasizes expansive growth, dense branching, and prolific seasonal coloration.
