Its maximum mature height is 100 feet high but the more typical mature height is 35 to 45 feet tall. Stone pine (Pinus pinea) , also known as the Italian stone pine and umbrella pine is a medium-sized coniferous tree. The stone pine, botanical name Pinus pinea, also known as the Italian stone pine, umbrella pine and parasol pine, is a tree from the pine family (Pinaceae). Conifer, evergreen tree, 40-80 ft (12-25 m) tall, similar width, crown broadly arched, umbrella-shaped, bark on older trees reddish or yellowish brown.Leaves (needles) in 2's, 10-15 cm long and about 2 mm wide, stiff, twisted, apex sharp, margins finely toothed (dentate), dorsal side with about 12 stomatal lines, ventral side with about 6, sheath 10-12 mm long.Cones usually solitary, terminal, occasionally grouped 2-3, broadly oval, 8-15 cm long and up to 10 cm wide, glossy brown, often up to 100 seeds per cone, seeds large and edible (pine nuts) and are collected commercially from trees stands and forests, especially in Spain and Portugal. The seeds (pine nuts, piones, pinhes, pinoli, or pignons) are large, 2cm (34in) long, and pale brown with a powdery black coating that rubs off easily, and have a rudimentary 48mm (532516in) wing that falls off very easily. Pinus pinea is also currently widely cultivated around the Mediterranean for environmental protection such as consolidation of coastal dunes, soil conservation and protection of coastal agricultural crops. Or, you could treat it not as a house plant but a summer plant. Examples are the Pineta of Jesolo and Barcola, the Urban Beach of Trieste. It will need water only every month or so under this care plan. The species was introduced into North Africa millennia ago, and is also naturalized in the Canary Islands, South Africa and New South Wales. [7] Another location in Greece is at Koukounaries on the northern Aegean island of Skiathos at the southwest corner of the island. Wild fires and overgrazing being the most important risks for P. pinea forests, fire protection and social measures that might reduce these hazards should also be addressed for the effective conservation of this typically Mediterranean pine.

Q: I bought a living Christmas tree this year from Meijer's. , College of Agricultural Sciences - Department of Horticulture, USDA Hardiness Zone Maps of the United States, Oregon Master Gardener Training: Identifying Woody Plants. The year-old seedlings are seasonally available as table-top Christmas trees 2030cm (812in) tall. Its nickname comes from its shape at maturity. EUFORGEN young. needle luster (length and density) enhanced with supplemental water during Its stiff needles in twisted bundles make for an interesting appearance, aided by five- to six-inch long cones that remain firmly closed on the tree for three years. The tree should be considered ornamental, much as is a poinsettia and discarded after Christmas, he said. Italian stone pine has tasty pine nuts. [2], Pinus pinea is a diagnostic species of the vegetation class Pinetea halepensis.[3]. Flower: Species is monoecious; males cylindrical, in tight cluster at branch tips; females small, reddish purple with loose scales at branch tips. Growth Habit: Very slow when young to moderate with age eventually reaching heights of 40 to 60 feet with a somewhat greater spread such as this mature specimen in Toulouse, France. Here, the temperature would fluctuate from slightly below freezing to perhaps 45 degrees on a sunny day.

Feed it every six weeks with a house plant fertilizer Form: Usually a medium sized tree up to 70 feet tall but can attain 120 feet, with an umbrella-shaped crown. In Italy, the stone pine has been an aesthetic landscape element since the Italian Renaissance garden period. Katrin Heer RT @KatrinHeer: Postdoc position on forest genetics for 4 +2 years @UniFreiburg - come and work with us on investigating the (epi)genetic b, EUFORGEN Form & Character: Evergreen, decurrent pine with a rounded, globular habit even when young becoming more wide spreading with age. This would likely induce dormancy for the remainder of our winter. Hrycaj said the grower is based in Half-Moon Bay, near San Francisco and also sells to Safeway stores and that chain has stores in climates much warmer than Michigan's where the tree is naturally hardy. Data in Brief 12, 662-666. It is often used for bonsai. It was first planted in Rome during the Roman Republic, where many historic Roman roads, such as the Via Appia, were (and still are) embellished with lines of stone pines. The tree is among the symbols of Rome and its historic streets, such as the Via dei Fori Imperiali. Small specimens are used for bonsai, and also grown in large pots and planters. In the Western Cape Province, the pines were according to legend planted by the French Huguenot refugees who settled at the Cape of Good Hope during the late 17th century and who brought the seeds with them from France. Pinus pinea has been cultivated extensively for at least 6,000years for its edible pine nuts, which have been trade items since early historic times. The conservation of forest genetic resources in the Mediterranean basin is a very complex task, as ecological and socioeconomic conditions are highly variable among countries. The tree can be gradually moved outside on warm days in April and May and returned to a protected area when frost is threatened during spring. long, juvenile needles small blue and and persistent when tree is In coastal California, for example, where known popularly as the Italian stone pine in tree guidebooks since 1956, this evergreen is widely grown from Hollywood to Palisades Park (Santa Monica), to Sylmar in the northern San Fernando Valley, and in Marina del Rey, after World War II. The tree is also known as Umbrella pine and its formal name is Pinus pinea. Chances are being inside in a warm, dry home has already led to a goodly amount of needle drop. in coastal or desert areas in the American Southwest. [12], Needles of a juvenile (left) and adult (right), Adult stone pines at Villa Borghese gardens, Rome.

As a result of many years of cultivation, the native distribution of the tree is unknown. Genetic conservation units - Appropriate silvicultural and management strategies should include the leaving of the highest possible number of seed trees before regeneration to promote maximum outcrossing and pollen flow. The tree is among the current symbols of Rome. As in other forest tree species, implementing an in situ conservation network where selected populations are allowed to naturally regenerate without introduction of exotic material is recommended. The prehistoric range of Pinus pinea included North Africa in the Sahara Desert and Maghreb regions during a more humid climate period, in present-day Morocco, Algeria, Tunisia, and Libya. Regions of autochthony such as Spain and the eastern Mediterranean, areas where ecological conditions are extreme (high altitude, low rainfall, high salinity etc. It has naturalized beyond cities in South Africa to the extent that it is listed as an invasive species there. The wing is ineffective for wind dispersal, and the seeds are animal-dispersed, originally mainly by the Iberian magpie, but in recent history largely by humans. Privacy Policy and Cookie Statement updated 7/1/2022). Twig: Moderately stout, ash-gray to gray-brown; buds ovoid with red-brown scales. More about this in a moment. You may be able to grow the tree as a house plant, caring for it inside for nine months of the year, letting it vacation outdoors for the other three months. It has destroyed most of the pine nut seeds in Italy, threatening P. pinea in its native habitats there. a forest stand or area that contains tree populations nationally designated for conservation of FGR. Italian stone pine Pinaceae Pinus The tree has been cultivated for its nuts in Europe for over 6,000 years, and harvested from wild trees for far longer. Place it near a sunny window in a cool room and away from sources of heat, such as furnace registers The answer: The tag was a mistake and should not have been put on the tree by its California-based grower, according to Peter Hrycaj, a floral buyer for Meijer stores. Juvenile leaves are also produced in regrowth following injury, such as a broken shoot, on older trees. Leaf: Evergreen needles, to 5 inches long in fascicles of 2, thin, straight, blue-green, persistent fascicle sheath.

Its contemporary natural range is in the Mediterranean forests, woodlands, and scrub biome ecoregions and countries, including the following: The Iberian conifer forests ecoregion of the Iberian Peninsula in Spain and Portugal; the Italian sclerophyllous and semideciduous forests ecoregion in France and Italy; the Tyrrhenian-Adriatic sclerophyllous and mixed forests ecoregion of southern Italy, Sicily, and Sardinia; the Illyrian deciduous forests of the eastern coast of the Ionian and Adriatic Seas in Croatia and Albania; and the Aegean and Western Turkey sclerophyllous and mixed forests ecoregion of the southern Balkan Peninsula in Greece. Knowing its current adaptive diversity is also a prerequisite to outlining its potential distribution area and the consequences it may suffer from environmental changes. In youth, it is a bushy globe, in mid-age an umbrella canopy on a thick trunk, and, in maturity, a broad and flat crown over 8m (26ft) in width. ), and areas where extensive populations currently exist, should be the primary targets for such a network. This is a half-mile-long dense stand of stone and Aleppo pines that lies between a lagoon and the Aegean Sea.[8]. The tag says to plant it outdoors after Christmas. Because of their history of overexploitation since agriculture emerged some 10 000 years ago, assessing whether current Mediterranean forests are really well adapted and truly natural is challenging, although necessary for any careful conservation strategy.This is the case for P. pinea, in particular. Hardy to USDA Zone 8 Its native range may be impossible to determine for man has expanded its growing range for thousands of years; its range now includes the Canary Islands, the entire Mediterranean region and into Turkey. So why was the tag included on trees sold in Michigan where winter survival is not likely? Stone pine grows well in dry and sunny areas with high temperatures but is also able to tolerate frost. Its growth, though, is limited on very loamy soils. Flowers & fruits: Monoecious (male and female strobili born If all this sounds like a lot of work, I must admit, I think it is.

However, today, the natural distribution is near the Mediterranean Basin, extending from Portugal to Syria. The trees wood is of low quality but used locally for furniture, while the resin is tapped and used for rosin. I would treat the tree just as buyer Hrycaj suggests: Enjoy it for as long as it looks nice and then discard. Will our winter be too cold? Landscape Use: This pine casts a light shade and has a rounded symmetry that is great for parks and residential neighborhoods. The stone pine is a coniferous evergreen tree that can exceed 25 metres (80 feet) in height, but 1220m (4065ft) is more typical.

A: Unfortunately your tree is not hardy outside - not in Britton nor anywhere in the warmest part of the Lower Peninsula. Stone pine is mainly known and is commercially important for its highly nutritional and edible seeds: pine nuts. Young trees up to 510years old bear juvenile leaves, which are very different, single (not paired), .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}24cm (341+12in) long, glaucous blue-green; the adult leaves appear mixed with juvenile leaves from the fourth or fifth year on, replacing it fully by around the tenth year. It prefers sandy, acidic soils but tolerates calcareous ones, as well. How tall will it get and is it a fast or slow growing tree? Fruit: Woody cone, 3 to 5 inches long, brown, broadly rounded, thick rounded cone scales unarmed; bearing large edible pine nuts. [11], The introduced western conifer seed bug (Leptoglossus occidentalis) was accidentally imported with timber to northern Italy in the late 1990s from western USA, and has spread across Europe as an invasive pest species since then. With this method, I'd put it in a cool but protected area that gets plenty of light, such as an unheated porch.
