Sweet William flowers from May to July with dense, flat flower heads in red, pink and white and is an old cottage-garden plant. It is biennial and self-seeds. The nectar sits in a narrow tube and is only partly accessible to honeybees; butterflies and long-tongued bumblebees reach it more easily. British measurements give around 551 micrograms of sugar per flower per day.
