Texas FFA Nursery Landscape Practice Exam

The definition of a woody perennial with more than one main trunk is accurately associated with shrubs. Shrubs are typically characterized as multi-stemmed plants that do not have a single trunk and generally grow to a height between ground level and about 13-15 feet. They are important in landscaping for their aesthetic appeal, ability to create privacy, and providing habitat for wildlife. In contrast, a tree usually has a single trunk that supports a tall, branching structure. Weeds are unwanted plants that grow in gardens or fields but aren't defined by their woody characteristics or their trunk structure. Flowers refer to the reproductive structures of flowering plants and do not describe the form of the plant itself. Thus, when considering the definition provided, shrubs stand out as the correct classification.
