I can definitely see why so many people find gardening calming. There's something satisfying about caring for a plant and watching it grow over time. The slower pace encourages patience, gets you outdoors, and gives you a break from screens and everyday stress.
Many gardeners say they enjoy flowers for their color and fragrance, while herbs like basil, mint, or rosemary are especially rewarding because you can use them in cooking. Others find vegetables such as tomatoes or peppers particularly satisfying because they can literally enjoy the fruits of their effort. In the end, the best plants are usually the ones you enjoy caring for and watching thrive.
