A wallflower is someone with an introverted or shy personality type (or in more extreme cases, social anxiety) who will attend parties and social gatherings, but will usually distance themselves from the crowd and actively avoid being in the limelight. They are also social around friends but not strangers, though once around friends, the strangers become less impactful. The name itself derives from the eponymous plant's unusual growth pattern against a wall as a stake or in cracks and gaps in stone walls. "Wallflowers" might literally stand against a wall and simply observe others at a social gathering, rather than mingle.
