Species: Pinus pinea L.

(Pinus pinea L.)
-> Genus: Pinus -> Family: Pinaceae -> Group: Gymnosperms

Habitus

  • tree growing to a height of 15 - 25 (30) m
  • crown is typical - umbrella-shaped (up to hemispherical) fairly high-set (no other pine tree has such a crown)
  • bark when young is gray to light gray
  • later the longitudinally cracked bark forms into flat plates, the surface of the plates is yellow-brown to reddish

Leaves (assimilation organs)

  • assimilation organs are needle-like
  • needles grow two at a time on brachyblasts - on smooth yellow-brown shoots
  • needles are grey-green, firm, deeply grooved on both sides, 10-15 cm long
  • two needles on brachyblast - subsection Pinea

Flowers

  • wood monoecious, flowers of different sexes, cone-shaped (similar to other pines)
  • flowers late spring to early summer

Fruits – seeds

  • the fruit is a cone, broadly ovoid to spherical when ripe, light brown to brown-red, shiny, 8 - 14 x 10 cm large
  • the navel is in the center of the labellum (section Pinaster)
  • the cone ripens in the third year in the fall and opens only in the fourth year
  • the seed is wingless with a hard shell (pine nuts - pignols), oval, light brown, grooved, 2 cm long

Extension

  • Tertiary relic
  • its original home is the coastal areas of Spain, France, Italy, the Balkans, Asia Minor, the eastern Black Sea and the coast of the Middle East
  • today it is no longer possible to say where it was brought by man and where it grew naturally, because it is a tree that has been culturally cultivated since the earliest times.

Ecology

  • grows on sandy soils and rocks near the coast
  • likes acidic soils

Significance

  • decorative with its typical appearance - a high-set, densely leafy umbrella-shaped crown
  • it was grown not only for its valuable wood, but also as "fruit", because its wingless seeds - "pine nuts" (pignols) taste like almonds and are used in confectionery (since Roman times)
