Can Norfolk Pines Be Planted Outdoors?: 1 Minute to Learn About Growing Norfolk Pines Outside

Norfolk Pines (Araucaria heterophylla), despite their popular use as indoor decorative trees, are actually native to subtropical regions and can be grown outdoors under the right conditions. Their natural habitat is on Norfolk Island in the South Pacific, where the climate remains mild year-round. To thrive outdoors, Norfolk Pines require temperatures that seldom drop below 35°F (1.5°C). In the United States, this means they're best suited for USDA hardiness zones 9-11, which include parts of southern California, Florida, and coastal Texas. Outside these zones, cold temperatures and frost can harm or even kill the tree.

When planting Norfolk Pines outdoors, choose a location with well-drained soil and full sun to partial shade. These pines can grow to impressive heights—sometimes over 50 feet (15 meters)—so make sure there’s ample vertical space. Regular watering is key during the tree’s establishment phase, but once mature, they are relatively drought-tolerant. As a designer, I always emphasize the importance of considering scale and lighting—placing a Norfolk Pine in your landscape can create a dramatic vertical accent or even serve as a living focal point. If you're planning a layout, digital tools like an AI floor planner can help you visualize how mature trees will fit within your overall outdoor design.

Tips 1:

Check your local climate and soil conditions before planting a Norfolk Pine outdoors. If you’re in a borderline zone, consider planting it in a large container so you can move it indoors during cold snaps, preserving both the plant and your landscape design. Remember, scale matters—think about sightlines and the eventual size when choosing a location in your yard.
