Description and Growing Information

General DescriptionLarge in size with most specimens having an irregular or unkempt form. Deep green needles in fascicles of five. Cones of this species are larger and heavier than most pines.
ID CharacteristicSpecimens in the natural landscape are easily recognized by their unkempt form personified by heavy winds.
ShapeTall, very broad and open canopy.
LandscapeThis species is truly a great evergreen to add to any landscape because of its beautiful deep green foliage and intriguing cones.
PropagationPropagate through seeds. For rapid and complete germination, seeds should be sown in individual pots followed by a cold stratification period of at least 30-90 days. It is best to plant seedlings out in their permanent locations early so that they may develop a strong root system.
CultivationLight sandy or gravely loam, well drained soils with acidic to neutral conditions. It requires full sunlight and will not tolerate shade but will withstand some humidity; once established it can survive drought.
Notable SpecimensStanford University, California, United States of America.
HabitatAlong the southern coast of California.
Bark/Stem DescriptionThe bark is smooth, and reddish brown in young specimens, eventually turning grey, becoming very rigid and scaly with maturity.
Flower/Leaf Bud DescriptionBuds are 2.5 cm long, ovular, cone shaped and pale brown in colour.
Leaf DescriptionDeep green, 5 needle fascicles are 2 mm wide and range anywhere from 20-30 cm long. They can be straight but sometimes have a slight curve to them from harsh winds.
Flower DescriptionPine trees don’t actually have flowers; they have “strobili” which serve the same purpose. Strobili are pollinated by wind and the tree is monoecious.
Fruit DescriptionThe Torrey Pine produces cones that are not only noticeably larger but heavier than most other cones. Cones are approximately 10-15 cm long, a striking grey almost silver colour. The cones have been known to stay on the tree for up to 10 years, slowly releasing their seeds.
Colour DescriptionFoliage is an attractive deep greenish-grey colour, cones are greyish silver, and the bark is brown but as the plant matures it turns grey.
Texture DescriptionMedium.
