Clover is the English name of the little three-leafed plant, from the Old English clafre, and a four-leaf "clover" has stood for good luck for centuries. It joins the wave of nature names like Willow and Juniper, with a cheerful, slightly whimsical sound. Clover entered the US top 1000 in 2021 and has risen every year since, from number 860 to number 517 in 2025, its highest rank yet.
