Pinus wallichiana 'Zebrina' (v)

Bhutan pine 'Zebrina'

A rare, evergreen, coniferous tree, capable of reaching 10m (30ft) high and 6m (20ft) in diameter. The bark is smooth and dark grey when young, becoming pale grey and fissured over time. The tree forms a broadly conical canopy, with the needles produced in groups of five at the tips of short stems. The needles are thin, hanging and soft to the touch, approximately 10cm (4in) long. Their colour is the main feature of this tree, being blue-green, with pale yellow bands. The cones appear on relatively young trees and are oval, to cylindrical in shape, pale-brown and around 15-25cm (6-10in) long. They are liberally coated with blobs of resin.
