Which of the following is NOT a woody plant?

Garlic mustard is classified as a herbaceous plant, which means it has non-woody stems that die back at the end of the growing season. This characteristic distinguishes it from the other plants listed, which are all woody. Woody plants typically possess hard stems that can persist year-round and contribute to their structure and longevity. In contrast, garlic mustard does not develop that woody structure and remains herbaceous throughout its life cycle, further clarifying its categorization as not being a woody plant. This clear distinction between herbaceous and woody plants makes garlic mustard the answer in this context.
