Features and characters of the individual

It looks like a cypress, but it isn’t one. This has led its being called “Lawson’s cypress” (in English) and “faux cypress” (in French). If you’re waiting for the bus at Arcades, take the time to observe this tree and you will see how the overhead parts of the tree are related to their underground parts. Scan the tree from the top right down to its base. It looks like it’s missing half of its pyramid-shaped crown. If you continue to follow your eyes along the trunk, down to the base, you will see that the tree is growing on top of a wall. How did its creeping roots grow in the soil? False cypresses are often planted to decorate parks and walkways. Here, this isolated tree creates intrigue with its unusual shape. But it’s a nice case study to see the relationship between a trees roots and top.
