A Greenwood Tree

One of the librarians’ recommendations at the RHS Lindley Library revealed an unexpected Christmas story about the Aspen, Populus tremula. The little gem of information was inside the pages of Christina Hart-Davies’ beautifully illustrated new book The Greenwood Trees: History, folklore and uses of Britain’s trees (2018).

All of a Quiver

Aspens are known for their constantly shaking leaves. The folklore suggests that the tree shakes all year, except on Christmas night. I was puzzled how a deciduous trees leaves would shake, but this is after all folklore. Why does the tree shake? It reputedly quivers in guilt because Jesus was crucified on a cross made from its wood. Scots’ superstitious fear of bad luck was so strong that they historically refused to use the Aspen’s wood at all. 

Populus tremula not Populus tremuloides

The tree in question is the British native Populus tremula as opposed to the North American Populus tremuloides. The tree is dioecious. This means that there are separate male and female trees. Ashbridge Nurseries state that they do not sell the female trees at all, as they produce vast amounts of seeds which can become a nuisance. The attractive, grey and red, male catkins emerge before the leaves in the spring. The leaves flutter until the autumn. Then, they turn a vibrant yellow before falling.

The Aspen’s life-span is relatively short for a tree at around 50-80 years. It reproduces via wind pollination, but is also known for its prolific suckering. The Aspen’s bark is a pale greenish-grey and smooth on young trees. It is marked with dark grey, diamond-shaped lenticels. Lenticels function as pores. The bark has a tendency to fracture or crack as the tree ages.
