StatisticsHeight: up to 1mWhen to seeMay to OctoberAboutWhite campion is a common wildflower that grows in fields, along hedgerows and roadside verges, and on waste ground. It flowers throughout the summer, but it's actually at night when the blooms produce a heady scent, attracting many feeding moths. White campion is often a perennial plant, which means it can live for a number of years, growing again each spring; but it can also be a short-lived annual or biennial.
