In bright sun in June or July, sulphur clover lives up to its name, with vivid flowers that are larger than the common white and red clovers. As the seeds ripen, the flowers fade to brownish orange and once you know what you are looking for, the leaves can be spotted for most of the year. Just like other clovers, they are 'trifoliate', meaning the leaves are split into three parts, but unlike other British clovers, they are grey-green and downy to the touch.
