Wallflowers are plants that typically grow in rocky or dry areas, known for their bright, colorful flowers. They belong to the genus Erysimum and are part of the mustard family, Brassicaceae. These hardy plants are often found in gardens and are appreciated for their ability to thrive in poor soil conditions. In addition to their botanical significance, the term "wallflower" is also used to describe a person who is shy or introverted, often standing apart from social activities. This metaphorical use highlights the idea of someone who may feel overlooked or out of place in social settings.
