Stone pine seed

Common name：Pinus pinea

The Stone Pine can exceed 25 m height, though is usually rather less tall, 12-20 m being more normal. As a juvenile tree it is a globe shape, slowly developing a characteristic umbrella-like shape, with a short trunk and very broad, smoothly rounded to nearly flat crown. The bark is thick, red-brown and deeply fissured into broad vertical plates. The flexible mid-green leaves are needle-like, in bundles of two, and are 10-20 cm long (exceptionally up to 30 cm). Young trees bear juvenile leaves, which are very different, single (not paired), 2-4 cm long, glaucous blue-green; the adult leaves appear mixed with juvenile leaves from the second or third year on, eventually replacing them fully. Juvenile leaves are also produced in re-growth following injury, such as a broken shoot, on older trees.
