- Pinus can be shrubs or large, evergreen trees, some species with attractive bark, developing an irregular outline with age and bearing long needle-like leaves in bundles of 2, 3 or 5; conspicuous cones may fall or remain on the tree for year.
- Pinus sylvestris, commonly called Scots pine, is a fast-growing, conical to columnar, medium sized conifer with distinctive flaking orange/red-brown bark. It develops an open-rounded, irregular crown as it matures. It is a very widely distributed pine that is native to northern Europe and northern Asia, but has also naturalized in parts of the northeastern and north-central U.S. It is the only pine that is native to Great Britain. Plants will vary in habit, hardiness and needle appearance depending on their specific native geographical growing region. Scots pine generally features (1) twisted, blue-green needles in bundles of two, (2) gray to light brown cones and (3) scaly orange/red bark in upper part but darker red-brown near the base.
