What is Stone pine?
Stone pine, Pinus pinea, is an evergreen conifer with a broad umbrella-shaped crown. Its seeds are harvested as pine nuts.
Botany and life cycle
1. Identity and native range Pinus pinea is a Mediterranean conifer in Pinaceae. Planted groves are not necessarily native stands. 2. How to recognize it Needles commonly grow in pairs. Mature trees can have a broad crown. Large woody cones contain thick-shelled edible seeds. 3. Flowering and reproduction Wind carries pollen to female cones. Seeds mature over more than one growing season, so visible cones do not directly predict a harvest.
Ecology, cultivation and uses
4. Habitat and ecology It suits sunny well-drained Mediterranean habitats. Crowns offer shade and shelter, while harvesting, fire and drought affect regeneration. 5. Cultivation and care Give space for its crown and roots. Water young trees during establishment, avoid waterlogged soil and maintain branches near buildings. 6. Uses and cautions Pine nuts are culinary seeds and can trigger allergies. Stone pine is not the pistachio tree, Pistacia vera.
