Answer: Bougainvillea are hardy only to about 40F. If frost is predicted, you can provide temporary protection when the plant is small. As it matures you'll probably have to cut away any winter damage on the tops of the plants. The roots should be able to manage a short frost and will send out healthy new stems in the spring. Oo La La grows 6-8' wide and only about 2' tall. It's not nearly as vigorous as Barbara Karst but it is a beautiful plant. Enjoy!
