Planting & Care

Select a location receiving abundant sunlight for optimal bract production. Plant in well-draining soil and water thoroughly at planting time to help roots establish. Once settled, this bougainvillea needs only occasional deep watering; paradoxically, drier soil conditions intensify the brilliant color display. Prune as desired to shape it into your preferred form. In colder climates, grow in containers and bring indoors during winter months.
