About Geranium versicolor L.
Geranium versicolor, commonly called the pencilled geranium, pencilled cranesbill, veined cranesbill, or veiny geranium, is a flowering plant species belonging to the Geraniaceae family. It is native to southeastern Europe, and has been introduced as an escaped garden plant to Ireland, Great Britain, France, the former Czechoslovakia, and the U.S. state of Pennsylvania. It is a semi‑evergreen perennial that grows to 45 cm (18 in), and is widely available from commercial plant suppliers. The Royal Horticultural Society considers it a good plant for attracting pollinators. Along with Geranium endressii, it is one of the parent species of the artificial garden hybrid Geranium × oxonianum.
