Araucaria heterophylla (Norfolk Pine)As an indoor plant, it is a small evergreen with saber like leaves that turn inward in an overlapping herringbone pattern on tiered branches. Indoors it prefers a bright, cool room (55 65 degrees F) and will reach heights of 9 feet. Use fertile, porous, sandy, peaty, slightly acidic, well drained potting soil. Full sun is normally best for developing compact symmetrical growth, but light afternoon shade may be needed to avoid possible foliage bleach
