Norfolk Island Pine: Keep Indoors—Not Cold Hardy Below 50°F (10°C)

No. The Norfolk Island Pine (Araucaria heterophylla) is a tropical/subtropical conifer native to Norfolk Island (South Pacific, 29°S). It cannot tolerate frost or sustained temperatures below 50°F (10°C). In temperate zones, it must remain a houseplant year-round. Summer placement outdoors is risky—nights often dip below threshold. If attempted, use a sheltered pot, monitor temps daily, and bring in well before autumn. Indoors: bright indirect light, moderate humidity, well-draining soil.
