Common rock-roseHelianthemum nummularium

Helianthemum nummularium, commonly known as common rock-rose, is a low-growing perennial wildflower native to Europe. It is recognized by its cheerful yellow, five-petaled flowers and small, oval leaves that inspired the species name nummularium, meaning “coin-like.” Despite its common name, it is not related to true roses; the name refers only to the resemblance of its delicate flowers. Each bloom lasts for just a single day, but the plant continuously produces new flowers throughout the season, creating a long display across sunny limestone grasslands and rocky slopes.
