The 'mouse' hiding in the fir cone

 

This a Douglas fir Pseudotsuga menziesii cone, easily recognisable by the papery bracts, resembling the hind legs and tail of a mouse, above each scale. Native American folklore has it that mice climbed the trees and hid amongst the cone scales when fires swept across the forest floor.

 The tree’s common name commemorates David Douglas, the Scottish botanist and plant collector who, in 1826, introduced it into cultivation here. Douglas led a colourful life before coming to an unfortunate end when he was gored to death by a bull in Hawaii, at the tragically young age of 35. The Latin specific name commemorates Archibald Menzies, another great Scottish plant collector who discovered the tree in 1792.

Douglas fir’s wind-dispersed, winged seeds are only about a centimetre long but grow into a giant tree in its native Pacific North West of America, where some are believed to have grown even taller than giant redwoods, reaching almost 400ft., before the finest specimens were felled for their exceptionally fine timber. Douglas firs planted in Britain grew very rapidly, with some now exceeding 200ft., making them amongst the tallest trees in the British Isles.
