A plant that has been grown indoors since the Victoria era. Tolerates a variety of growing conditions. Nice to decorate at Christmas time. It is not a pine tree!!!
Plant Type
All Plants, Indoor Foliage
Hardiness Zone
11
Sunlight
Tolerates lower light conditions but does best in bright light to full.
Moisture
Prefers to be kept evenly moist with higher humidity but tolerates average house. The main cause of needle drop is allowing the plant to get too dry, to many times.
Growing Media
average house
Temperature
average house, minimum of 50-55 degrees
Flowers
Female cones are produced on plants 15 years or older and male on 40 years or older. Heavy seed producton every 4-5 years.
Leaves
short green needle-like
Stems
The branches produce short green needle-like foliage. They radiate from the central stem at a wide angle creating a layered (pagoda-like) look.
Dimensions
Can reach over 200' in native areas but seldom over 6-10' in the house. Grows very symetrical as a young plant.
Maintenance
Many times the plant loses the bottom branches. I have topped plants and they slowly formed side branches filling in some of the bare area. Multiple tips also will form.
Propagation
The most common way to reproduce Norfolk Island Pine is using fresh seeds. Seeds lose their viability quickly. Cuttings are difficult and the only area that produces true plants is the tip. Side branch cuttings give you prostrate plants.
Native Site
Edemic to lowland areas of Norfolk Islands (900 miles northeast of Sidney Australia)
Misc Facts
They exhibit a strong apical dominance and don't readily form side branches, unless they are topped. They have a tendency or should I say a bad habit of dropping their bottom branches. We have cut Norfolk's in half and to my surprise they will form side branches. Often sold as decorated Christmas trees.
Author's Notes
Many people don't know that these plants can be cut back very hard. We did this many times to donated plants that were lopsided or leggy. The only draw back is recovery is very slow. If I were to do this with one of my house plants I would cut back hard in early May and grow it outside when weather warms up. Be patient....... When in Hawaii I saw many Norfolk Island Pine over 30-40 feet tall.
