Araucaria heterophylla aka Norfolk Island Pine

Taxonomy

Araucaria heterophylla, also known as Norfolk Island Pine or Star Pine, is a stately evergreen tree that is endemic to Norfolk Island, an external territory of Australia in the Pacific Ocean. While it is often used as a living Christmas tree due to its symmetrical shape, it is not a true pine but a member of the Araucaria genus in the Araucariaceae family. This family includes other trees such as the monkey-puzzle tree and is concentrated in the South Pacific, particularly in New Caledonia. The Norfolk Island Pine has a graceful pyramidal shape with wide-spaced branches symmetrically arranged in whorled, horizontal tiers around a single straight trunk. In its native habitat, it can reach heights of up to 200 feet. When grown as a houseplant, it is important to choose a plant with multiple trunks to avoid a bare appearance as it grows taller. While not poisonous, ingestion of the pine needles can cause severe stomach problems in children and pets. To thrive, the Norfolk Island Pine requires ample room in open, full sun locations with well-drained soil.

How to care for Norfolk Island Pine

Difficulty

Norfolk Island Pine requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

Water

Norfolk Island Pine should be watered regularly, allowing the soil to dry out between waterings.

Soil

Norfolk Island Pine loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Norfolk Island Pine prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Toxicity

Norfolk Island Pine is not known to cause harm to humans or pets.

Humidity

The Norfolk Island Pine does not necessitate supplementary humidity. Plants primarily absorb water through their roots, rather than their leaves. Hence, the most effective way to supply humidity to your plants is by watering the soil.

Fertilizer

The Norfolk Island Pine should be transferred to a new pot once it has increased in size two-fold, or on an annual basis, whichever occurs earlier. Replacing the soil with fresh potting soil containing all the necessary nutrients, is sufficient enough to support the growth of the plant, thus avoiding the need to use fertilizer. It's important to note that plants derive their energy from the sun and not fertilizer.

Growth-pattern

New growth will sprout from the top of the plant as it grows upwards.

Region of origin

Norfolk Island Pine’s native range is South America and Oceania.
