Bougainvillea
Bougainvillea glabra
The colorful "flowers" are actually papery bracts (modified leaves) surrounding tiny white true flowers in the center — they retain color for weeks longer than real petals would.
How to care for bougainvillea
Withhold water to trigger blooming — bougainvillea flowers on stressed plants and produces only leaves when over-watered. Plant in well-drained soil and prune after each bloom cycle to maintain shape.
Garden uses & design ideas

Use the garden planner to test spacing around its mature size: 15-40 ft long. Regional note: It needs frost-free warmth and sharp drainage; cold-zone gardeners should grow it in a pot that can be moved indoors before chilly nights.
