Discovered on Norfolk Island in the South Pacific by Sir Joseph Banks in 1793, this handsome conifer reaches a height of 200ft/60m in its natural habitat. As a houseplant, however, it will grow to a more suitable 3-6ft/90cm-1.8m.

It is a slow grower and after reaching this height is past its best. The Norfolk Island pine is appealing because of its horizontally held branches covered with V2-in/13-mm-long needles, which are bright green in the spring, and turn dark green over time. The plant should last for many years and can be used as a Christmas tree.
Araucaria requires a bright, well-lit location and enjoys a spell outdoors on mild days. Frequent misting is important; this plant likes freely circulating air, but not dry heat, and in summer it needs an even more-humid atmosphere.
Dry, yellowing needles indicate that conditions are too hot and dry. Move the plant to a cool, well- ventilated location, and water and mist it more frequently.
Aphids and mealybugs can attack this plant. Watch for signs of infestation and spray with a suitable insecticide.
