Closely related to both Araucaria (Monkey Puzzle) and Wollemia nobilis. This is a prehistoric tree originating during the Jurassic period (between 190 and 135 million years ago). Leaves are 3 to 7 cm long and 1 cm broad, tough and leathery in texture, with no midrib; they are arranged in opposite pairs or whorls of three on the stem. The seed cones are globose, 5 to 7 cm diameter. The trunk has a flaking bark.
Agathis australis can grow to heights of 40 to 50 meters and trunk diameters big enough to rival Californian Sequoias at over 5 meters. Growth is fast and large trees are generally aged between 500 and 1000 years old. It can survive temperatures down to -7°C and is quite happy growing in Cornwall in the UK.
