Ixeris stolonifera

Ixeris stolonifera, commonly called creeping lettuce,[1] is a species of flowering plant in the family Asteraceae. It is native to east Asia, where it is found in China, Japan, and Korea.[2] It is a common and widespread species in Japan.[3]

Its natural habitat is on open mountain slopes, often is rocky areas with shallow soil. However, it is also found in disturbed areas such as cultivated fields and abandoned ground.[3][2][4] It has naturalized locally in the northeastern United States.[5][6]

Ixeris stolonifera is a low, stoloniferous perennial, with flowering scapes growing to approximately 15 cm (5.9 in) tall. It produces yellow heads of flowers in spring.[3] It can be confused with the similar-looking Ixeris japonica, but I. stolonifera is distinguished by its smaller inflorescences, smaller fruits, and more ovate-orbicular leaves.[4][7]
