Shining Cranesbill (Geranium lucidum), sometimes known as ‘gentleman’s buttons’, is a charming, glossy-leaved annual wildflower that brightens walls, banks, and rocky spots throughout the British isles.
It gets its common-name from its distinctive shiny, reflective leaves, which set it apart from relatives like Herb Robert (Geranium robertianum). The leaves are rounded or kidney-shaped, divided into 5 to 7 lobes cut about halfway, often with a glossy green surface that can flush red. Stems are brittle, fleshy, hairless, and frequently reddish, growing up to 35 to 40 cm tall (though often shorter and sprawling).
