Gracefulness is often referenced by simile, with people often being described as being "as graceful as a swan", or "as graceful as a ballerina". The concept of gracefulness is applied both to movement, and to inanimate objects. For example, certain trees are commonly referred to as being "graceful", such as the "Betula albosinensis", "Prunus × yedoensis" (Yoshino cherry), and "Areca catechu" (betel-nut palm).
