Norfolk Island Pine (Araucaria heterophylla) is a tropical evergreen that thrives exclusively indoors in Ontario's climate, unable to tolerate temperatures below 40°F (4°C). Success depends on providing bright, indirect light and maintaining consistent humidity—particularly critical during winter when indoor heating dries the air. This elegant, columnar plant adds architectural interest to any space while requiring minimal pruning. Ideal for bright rooms with stable temperatures and away from cold drafts.
