Why love plants?
Why not? With all the varieties of tree's presenting their beauty to the human eyes independently scattered and beautifully arranged to heighten the mood stimulations of happy thoughts. A study looking at the most calming image found the combination of green plants and blue water to be the most attractive and calming.
Plants are healthy. They promote health and well-being as well as you getting to nurture something alive. It's so cool to plant something in the ground, fertilize, water, and care for it all while watching it grow and bloom. I love my plants. They help people with stress and anxiety, too.
