Briar is a type of thorny plant, often found in the wild, that belongs to the rose family. It typically features dense, tangled branches and can produce small flowers and berries. Briars are known for their sharp thorns, which can make them difficult to navigate through in natural settings. In addition to its natural habitat, the term "briar" is also used in the context of briar pipes, which are smoking pipes made from the wood of the briar plant. This wood is valued for its heat resistance and ability to absorb moisture, making it a popular choice among pipe smokers.
