Appearance
It is a herbaceous perennial growing throughout Europe in damp, open locations. As one common name suggests, it is a larger plant than related "Lotus" species, growing 20–80 cm tall, with leaflets 10–25 mm long and 10–20 mm broad. Five to twelve golden-yellow flowers 10–18 mm long are borne in an umbel at the tip of the upright stem.Unlike related species, the stem is always hollow, and the sepals turn back at their tips – these sepal tips form a characteristic "green star" at the end of the flower bud. The peak flowering period in the United Kingdom is June and July.
