| General Description | Western White Pines tolerate a variety of soil condition from peat bogs, dry sandy soil to rocky conditions. |
| ID Characteristic | The needles are straight, flexible, triangular and bluish-green in colour. The needles also have lines of white spots, which have 5 needles per fascicle. The bark is dark grey and is broken into rectangular scaly plates. |
| Shape | The Western White Pine is a tall, straight and pyramidal shaped tree. As it matures to its full height the lower branches fall off and can leave up to 25 m clearance under the tree. |
| Landscape | It can be used as a windbreak or screening. It is also sometimes planted in parks or in restoration projects. However, the timber is very valuable and is used to make windows, doors, and furniture. |
| Propagation | Western White Pines are normally propagated through seeds. The seeds must go through cold stratification in the freezer for about 60-90 days. Then soaked in lukewarm water for 1-2 days. Once forty-eight hours have passed place the seeds in a zip-lock bag and put in the fridge for another 60-90 days. After completing these steps plant the seed in a pot that is 1 part pine bark, 1 part peat moss and one part garden soil or potting mix. Place the pot in full sun. |
| Cultivation | Grows best in well-drained sandy or gravely loam. Prefers a pH range of 4.5-6.8 and a location with full sun. |
| Pests | White Pine Blister Rust is a common fungus that effects Western White Pines. The first signs are chlorotic spots on the needles. The tree eventually produces orange cankers. The fungus girdles the branch causing it to die over a few years. If not treated in time the fungus will move throughout the tree and kill it. |
| Habitat | Western White Pine can tolerate a variety of soil conditions from peat bogs, dry sandy soil to rocky conditions. However in nature they seem to prefer growing in moist rich valleys or on gentle slopes. They are found in the mountains of Western Canada and the United States

| Bark/Stem Description | When the tree is young the bark is thin, smooth and a greyish-green. As the tree matures the bark becomes dark grey and broken into rectangular scaly plates 2-4 cm thick. |
| Flower/Leaf Bud Description | Buds are slender, bluntly pointed with overlapping brownish scales. Can be up to 10 mm long. |
| Leaf Description | Needles are 5-10 cm long and arranged 5 needles per fascicle. They are soft, slender, straight, flexible and triangular. The needles are bluish-green with lines of white dots. Bundle sheaths are deciduous in the 1st season. |
| Flower Description | Flowers are monoecious. Male flowers are greenish-yellow, small and are located on the tips of the branches. Female flowers are greenish-pink, round and larger then there male counterparts. They are located on the tip of the branches of the upper crown. |

Once cones are mature they drop to the ground in October. However, trees do not produce viable seeds until they reach maturity, which can take up to 70 years. |
| Colour Description | The needles are bluish-green with lines of white dots. On the tips of the higher branches there are flowers. The male flowers are yellow and the female flowers are pink. Once the cones start to develop they are green but eventually turn brown as they mature. The bark is greyish-green and smooth when the tree is young but later becomes dark grey and platy. |
| Texture Description | Medium textured plant that maintains its texture all year round. |
