Mouse ear is a term often used to describe the small, fuzzy leaves of plants like Cerastium and Veronica. However, there are many other synonyms for this unique feature. One such term is "lambs' ears," which refers to the velvety leaves of the Stachys byzantina plant. Other synonyms include "bunny ears," often used to describe the ears of cactus species like Opuntia microdasys, and "cat's paw," which is the common name for the groundcover plant Antennaria dioica because of its furry texture. Despite their various names, these mouse ear-like leaves are prized by gardeners for their softness and add a distinct and charming touch to any landscape.
