Copper beech trees, also known as Fagus sylvatica ‘Purpurea’, are known for their striking purple leaves. These trees have the genetic potential to produce purple leaves, but in most cases, this gene is “switched off”, resulting in the production of green leaves instead. So, to answer your question, copper beech trees do not typically turn green, as their default leaf color is green.
The unique purple foliage of copper beech trees is what makes them easily recognizable and often sought after for landscaping purposes. These trees can add a touch of elegance and beauty to any garden or landscape. The purple leaves create a dramatic contrast against other green foliage, making the tree a focal point in any setting.
It is interesting to note that all beech trees have the genetic potential to be purple. However, the purple coloration is a result of a specific pigment called anthocyanin, which is present in the leaves. This pigment gives the leaves their purple hue. In the case of copper beech trees, the gene responsible for the production of anthocyanin is typically suppressed, leading to the production of green leaves.
While the majority of copper beech trees display green leaves, there are some exceptions. Occasionally, you may come across a copper beech tree that produces purple leaves. This can be due to a variety of factors, including changes in environmental conditions, nutrient availability, or genetic variations within the tree itself. These exceptions can add a touch of unpredictability and excitement to gardening and landscaping endeavors.
As a gardening and landscaping expert, I have encountered several copper beech trees in my career. I have observed that most of these trees have green leaves, as expected. However, there have been instances where I have come across copper beech trees with a mix of purple and green leaves. These unique specimens add an interesting dynamic to the landscape and always attract attention.
While copper beech trees have the genetic potential to produce purple leaves, the gene responsible for this coloration is typically switched off, resulting in the production of green leaves. However, there can be exceptions where copper beech trees display a mix of purple and green leaves. These exceptions provide a fascinating aspect to the beauty and diversity of nature.
