For many young adults, the act of nurturing indoor plants has evolved into a meaningful lifestyle, often referred to as "plant parenting." This trend sees people creating lush, green spaces in their homes, complete with shelves stacked with potted plants, bathroom setups that resemble tropical greenhouses, and even phone reminders for watering. These individuals, known as "plant parents," treat their plants with the care and attention typically reserved for children, reflecting a growing emotional connection to living things. This phenomenon occurs in a broader social context where low birth rates are becoming more common. In France, for instance, about a quarter of young adults do not want to have children, and the ideal number of children for French women has decreased over the years. In this setting, caring for plants offers a less demanding form of parenting, fulfilling a deep human need to care for living beings without the complexities of raising children. For sociologist Serge Guérin, this trend taps into an ancient human instinct: "Plant parenting responds to a fundamental anthropological need of humanity: to take care." It allows individuals to experience the joy of nurturing life without the pressures of traditional parenting. The emotional impact of plant care is significant. A survey found that 33% of French people talk to their plants, 19% give them names, and 19% even consider the potential for plant-related tensions in the event of a separation. In Spain, nearly 7 out of 10 millennials identify as plant parents, and more than 8 out of 10 believe their plants have improved their physical and mental health. According to Guérin, this fascination with plants is ageless: "Vegetable life becomes a common center of interest without age concept: it fascinates as much a 5-year-old child as an 85-year-old person." The sense of mutual aid and trust also plays a role, as people often ask neighbors to care for their plants during vacations, creating a bond of responsibility and support. From a psychological perspective, caring for plants activates several well-being circuits in the brain. Tending to a living being, even a plant, stimulates the secretion of oxytocin, a hormone associated with calm and trust. Exposure to green, natural leaf shapes also reduces the activity of the amygdala, the brain's fear center. This aligns with the theory of biophilia, proposed by biologist Edward O. Wilson, which suggests that humans have an innate attraction to living things. A study published in the Journal of Physiological Anthropology found that participants who repotted indoor plants experienced lower stress levels and felt more relaxed than those who performed a computer task. In France, a survey by OpinionWay found that 74% believe plant care improves mood, 51% think it reduces stress, and 60% believe it enhances air quality and overall well-being. The appeal of plant care can also be understood through the lens of attachment theory, developed by John Bowlby. Humans have a natural need for a "secure base"—a stable presence that offers reassurance and a foundation for exploration. For many young adults dealing with eco-anxiety, unemployment, or stress from technology, plants provide a nonjudgmental, comforting presence. They offer a sense of control over a micro-world that one can manage, from choosing the right species to setting watering schedules. However, when this passion becomes an obsession, it can lead to warning signs such as compulsive buying, excessive spending on plants, social withdrawal, or intense distress when a plant dies. Despite these potential risks, the presence of plants in the workplace is often seen as positive, with 65% of employees believing they promote conviviality and 77% thinking they make the work environment more pleasant. Ultimately, the trend highlights a deeply human need to connect with living things, with oneself, and with others.
