A "wallflower" is a term used to describe a person who is shy or introverted, often remaining on the sidelines during social events. They may feel uncomfortable in large groups and prefer to observe rather than participate actively. This behavior can lead to feelings of loneliness or being overlooked, especially in settings like parties or dances. The term also refers to a type of plant, specifically from the genus Erysimum, known for its bright yellow, orange, or purple flowers. Wallflowers are often found in gardens and are appreciated for their ability to thrive in rocky or poor soil, symbolizing resilience and beauty in challenging environments.
