General Description

Among the largest and oldest trees in the world, kauri pine's lance-shaped leaves, exfoliating bark and massive trunk and canopy make it among the most magnificent trees for frost-free landscapes. A cone-bearing evergreen tree that was vital in building masts for ships during South Pacific exploration, it is native to the North Island of New Zealand. It is narrowly pyramidal in form when youthful, but will slowly become a massive, broadly spreading tree with great age. Its tan and light gray bark is knobby and corky, shedding in large flakes. The sap is resinous.

The light green young foliage can have reddish tints when first emerging. The are thin, leathery and lance-shaped, becoming dark gray-green at maturity. In spring, male and female cones appear in the same tree (although young trees tend to be one-gendered at first). Pollen is shed from the cylindrical male cones whilw the more rounded female cones are pollinated by the wind and become woody green cones that shed winged seeds.

Grow kauri pine in full sun protected from chilly winds in any moist but well-draining soil. It will become a terrific lawn or campus specimen tree in regions free from frosts and have ample moisture year 'round. In its native land this species is considered an endangered species because of historical timber exploitation.
