The geranium is a perennial with a long flowering time. Geranium is the botanical name and common name of the Cranesbill. There are over 600 species and varieties. Crane’s-bills come in all colors except yellow and orange. The petals are beautiful and often have delicate lines or spots.
Sometimes the Cranesbill is confused with the indoor plant Pelargonium. The latter is the one from the Dutch saying ‘sit behind the geraniums’. This means if you’re growing old you can ‘sit behind the geraniums’, aka do nothing, peer out of the window.
