Umbrella Pine Pinus pinea Play pronunciation

Stone Pine is a needled evergreen tree with a single trunk and branches at the top radiating out like an umbrella. It is a native of the coastal dunes and low hills of the Mediterranean countries. It is a medium sized tree in terms of height, maturing at 60 feet tall, but has a large trunk size at 40 feet. The edible pine nuts (pignolis) are soft and rich in oil and can be eaten raw or roasted. In the first few years after planting, the tree has a shrubby form. As it matures, the trunk grows thicker and taller, shedding lower branches. Eventually, it develops the umbrella shaped canopy. The needles are bright green. The genus name comes from the Latin name for pines. The species name means relating to pine.

Stone Pine does best in full sun, sandy to loam soil with a slightly acidic PH, and dry to medium moist conditions. Once established, the tree tolerates drought and most soil types, but it does not do well in poorly drained soil. It prefers cool summers and is not commonly found in southern climates. It has succeeded on the California coast. 

Small, young Stone Pines are sold as indoor Christmas tree in some areas and, if the soil and climate conditions are favorable, can be planted outside after the holidays. They can also be used as seasonal indoor plants, but they will eventually grow out of that role.

Insects, Diseases, and Other Plant Problems: 

Pine needle scale, Sawflies, borers and moths can be pests.  It can suffer from fungus Diplodia pinea and Mycosphaerella pini or red band needle blight. This tree is susceptible to wind damage.
