Camellias are evergreen in many parts of the country with mild enough winters. But when your winters reach Zone 6 ratings like in the northeast, they may drop foliage and leaf out in the spring. Water deeply the night before and maintain 3-4" of mulch. Consider protecting with sheets if practical. You may want to inquire with regional members of the Atlantic Coast Camellia Society near you to see what you can expect regarding leaf loss in your winters if left outside http://www.atlanticcoastcamell...
