Conifers Trees

A tall-growing, evergreen pine requiring plenty of space to grow, reaching up to 30m (100ft) when mature, with an oval to conical-shaped canopy. The trunk can reach (1.3m) (4⅓ft) in diameter, with red-brown bark when young, becoming grey-brown when mature. Dark green needles are produced radially along the stems in bundles of two, up to 15cm (6in) long and can remain on the tree for up to 3 years. The cones which reach 6cm (2½in) long, are an attractive glossy brown when newly mature and narrowly oval-shaped when closed, broadly oval-shaped when open. They can remain on the tree for several years.
