Will a bougainvillea live over the winter months?

Bougainvillea is typically not cold-hardy and may not survive winter in areas with frost or freezing temperatures. In regions with mild winters, it can remain evergreen, but in colder climates, it should be brought indoors or protected with frost cloths. If grown in pots, it's advisable to bring them indoors or to a sheltered location during winter. Proper care, such as reducing watering and providing adequate light, can help them survive the colder months.
