Iris humilis is a species of flowering plant in the family Iridaceae. It is a rhizomatous perennial, with a wide distribution range from Europe to China. It has sword-shaped leaves, a short stem and yellow flowers with an orange beard. It is cultivated as an ornamental plant in temperate regions. It has the common name of sand iris. Although this name normally refers to Iris arenaria, which was formerly once thought to be a subspecies of Iris humilis, it is now a separate species in its own right. Iris humilis is also known as low iris and yellow iris. It is known as Sand-Schwertlilie (meaning sand iris) in Germany. The Latin specific epithet humilis refers to low growing or dwarfish. It was first published and described by German-Russian botanist and geographer Johann Gottlieb Georgi in Bemerkungen einer Reise im Russischen Reich in 1775. Most parts of the plant are poisonous.
