Answer: Bougainvillea is hardy in USDA Zones 9 - 11 so you should be able to plant yours in the ground. B. glabra is a bit hardier - but you can count on frosts cutting it to the ground. Here in my Zone 8 garden they usually return in spring if well mulched and kept on the dryish side. You can plant bougainvillea in a container and take it indoors, but it isn't necessary in your gardening region and the plants typically are not very happy indoors.
Best wishes with your new bougainvillea!
