Yellow water-lily (Nuphar luteum) is an aquatic plant that thrives in waters with a muddy bottom, where its roots are anchored. Only the flowers and leaf blades reach the water surface. The flowers with five shiny yellow petals reach up to 4 cm in diameter. Long-petioled leaves have 10–20 cm long floating leaf blades with a heart-shaped base. It is a poisonous plant.
Its habitat is sensitive to changes, therefore the yellow water-lily is a threatened plant species. In the Red List of endangered ferns and seed plants of Slovenia it is defined as a vulnerable species.
