What is the name of the wood at the branch base that wraps around the trunk wood when a branch joins a larger parent stem?

The term 'Branch Collar' refers to the specialized area of tissue that forms at the base of a branch where it joins the trunk of a tree or shrub. This area is crucial for the health of the plant, as it is created by the plant to help heal the wound when a branch grows and can also play an important role in protecting the trunk from decay and disease. The branch collar contains specialized cells that assist in the growth and healing processes, ensuring a stronger attachment and a barrier against pathogens.

In contrast, the other terms do not accurately describe this unique anatomical feature. While 'Branch Border' and 'Branch Bifurcation' refer to other concepts in plant anatomy and growth, they do not denote the protective tissue around the branch. 'Branch Attachment' is a more vague term that does not specifically address the unique structure of the branch collar, which is essential for the tree's structural integrity and resilience. Understanding the role of the branch collar is key for anyone involved in landscape contracting, as it emphasizes the importance of proper pruning techniques that respect this natural protection mechanism.
