About

Despite its name, the Douglas-fir is not a true fir — it belongs to its own genus, Pseudotsuga, and is one of the tallest trees in the world, capable of exceeding 100 m in old-growth forests. Its cones are immediately recognisable by three-pronged papery bracts that poke out between every scale, resembling a mouse's hind legs and tail tucking for shelter.
