The same tree species may look completely different when grown in different locations. This is due to variations in environmental and growth factors that impact the tree as it grows.
Environmental and growth factors can include factors such as the amount of sunlight, the amount of rainfall, the soil quality, and other factors. The differences can lead to differences in the growth rate of the tree, the size of the tree, the shape of the tree, and the type of leaves that the tree produces. These differences are often the result of environmental and genetic factors that impact the tree as it grows.
Two oak trees, of the same age and grown from the same oak acorns, can look significantly different from one another. One oak tree grows tall and narrow, competing with other trees in the same environment. The other oak tree spreads wide and low to the ground, with a thicker trunk compared to its height. Neither of these oak trees has grown in a shape that is not typical of oak trees. For Semi Mature Trees, consider https://www.naturefirst.co.uk/semi-mature-trees/
The plasticity of individual species is often one of the most underappreciated variables in the specification of trees. For instance, when a buyer purchases a tree species from a photograph of a single individual in a certain environment, the buyer is not obtaining a full understanding of the potential forms of that species.
The competition between trees for light and resources is the most obvious driver of the differences in tree forms. Trees that grow in proximity to other trees have to compete for light and resources, leading to the development of taller trees. In contrast, trees that grow in open spaces do not need to compete for resources, resulting in the growth of trees with different forms than those that grow in the proximity of other trees.
